Translocation (botany) From Wikipedia, the free encyclopedia. Translocation in plants means the movement of liquids from place to place. Movement of water from the soil to the leaves is done in xylem vessels. Transpiration, the evaporation of water from leaves, causes a pull on the water column which and the water to move upwards.rom Wikipedia, the free encyclopedia.

- During cotranslational translocation, the ribosome provides the motive power that pushes the growing peptide into the ER lumen. During posttranslational translocation, additional proteins are necessary to ensure that the peptide moves unidirectionally into the ER membrane.

Protein biosynthesis Protein synthesis is the process whereby biological cells generate new proteins; it is balanced by the loss of cellular proteins via degradation or export. Translation, the assembly of amino acids by ribosomes, is an essential part of the biosynthetic pathway, along with generation of messenger RNA (mRNA), aminoacylation of transfer RNA (tRNA), co-translational transport, and post-translational modification.

- Definition. noun. A step in protein biosynthesis wherein the genetic code carried by mRNA is decoded to produce the specific sequence of amino acids in a polypeptide chain. The process follows transcription in which the DNA sequence is copied (or transcribed) into an mRNA. step in protein biosynthesis wherein the genetic code carried by mRNA is decoded to produce the specific sequence of amino acids in a polypeptide chain.

Bacterial translocation in humans T1 - Bacterial translocation in humans. AU - Lichtman,Steven M. PY - 2001. Y1 - 2001. N2 - Bacterial translocation is a phenomenon in which live bacteria cross the intestinal barrier. The definition may be broadened to include transmural passage of bacterial cell wall components such as lipopolysaccharide and peptidoglycan polysaccharide.

Translocation Photo by: Anette Linnea Rasmus. Translocation is the movement of materials from leaves to other tissues throughout the plant. Plants produce carbohydrates (sugars) in their leaves by photosynthesis, but nonphotosynthetic parts of the plant also require carbohydrates and other organic and nonorganic materials.

- For signal transduction over long distances in cells or between cells, see Transduction (physiology). Signal transduction refers to the transmission of a molecular signal in the form of a chemical modification by recruitment of protein complexes along a pathway that ultimately triggers a biochemical event in the cell.

- In group translocation, chemical modification of molecule to be transport is done into the cell. Group translocation is type of active transport because metabolic energy … is used during uptake of the molecule,. In bacteria the best known group translocation system is phosoenolpyruate: sugar phosphotransferase system (PTS) PEP + SUGAR ----- PYRUATE + sugar-phosphate In E.coli the PTS consists of two enzyme and a low molecular weight heat-stable protein(HPr)

Transgene From Wikipedia, the free encyclopedia. A transgene is a gene or genetic material that has been transferred naturally, or by any of a number of genetic engineering techniques from one organism to another. The introduction of a transgene has the potential to change the phenotype of an organism. In its most precise usage, the term transgene describes a segment of DNA containing a gene sequence that has been isolated from one organism and is introduced into a different organism.

- Background —Gut translocation of bacteria has been shown in both animal and human studies. Evidence from animal studies that links bacterial translocation to the development of postoperative sepsis and multiple organ failure has yet to be confirmed in humans.

- Glycation. Glycation is the result of typically covalent bonding of a protein or lipid molecule with a sugar molecule, such as fructose or glucose, without the controlling action of an enzyme. All blood sugars are reducing molecules.Glycation may occur either inside the body or outside the body.lycation is the result of typically covalent bonding of a protein or lipid molecule with a sugar molecule, such as fructose or glucose, without the controlling action of an enzyme.

Bacterial translocation in humans The purpose of this review is to evaluate the data from studies in humans on the occurrence of bacterial translocation and, more importantly, to evaluate its role as a cause of death in humans. Studies from trauma and intensive care centers often imply that bacterial translocation is a major contributor to sepsis, shock, and multisystem organ failure in humans. However, the data reviewed herein do not support that view clearly. Carefully designed studies are needed to determine the relevance of bacterial translocation in human disease. AB - Bacterial translocation is a phenomenon in which live bacteria cross the intestinal barrier.

ReviewCo-translational targeting and translocation of proteins to the endoplasmic reticulum â There are several distinct pathways, which target secretory protein to the ER. In this review, we focus on the universally conserved co-translational translocation pathway, which also integrates membrane proteins into lipid bilayer [1] and [2] .Alternative ER targeting pathways, which are not directly coupled to translation, are covered elsewhere in this issue (Johnson et al, in this issue).o-translational protein targeting to the endoplasmic reticulum (ER), represents an evolutionary-conserved mechanism to target proteins into the secretory pathway.

- A: Translocation mutations take place when a portion of a chromosome is relocated. The genes from one chromosome can move to another position on the same chromosome; alternatively, they can become incorporated into a different chromosome.

Transamination Transamination. The transfer of an amino group from one molecule to another without the intermediate formation of ammonia.Enzymatic reactions of this type play a prominent role in the formation and ultimate breakdown of amino acids by living organisms.he enzymatic transamination reaction, which was discovered in 1937 by the Soviet biochemists A. E. Braunshtein and M. G. Kritsman, is an important link in the process of synthesis and deamination of many amino acids in animals, plants, and microorganisms.

As a result, the ribosome cannot bindaminoacyl-tRNA, and no further amino acidscan be added to the chain.Translocation is an intrinsic property of theribosome that requires a major change in struc-ture (see Section 8.17, Ribosomes Have SeveralActive Centers).

Translocation More Answers. Translocation is the movement of materials from leaves to other tissues throughout the plant. Plants produce carbohydrates (sugars) in their leaves by photosynthesis, but nonphotosynthetic parts of the plant also require carbohydrates and other.Translocation-movement of food and nutrients in the plant.he transportation of food through xylem to different parts of the plant is called translocation.

- Transamination (or aminotransfer) is a chemical reaction that replaces an amine functional group with another amine. In many applications, an amino acid is the substrate. The other substrate is a keto acid, which contains a keto (=O) group. In transamination, the NH 2 group on one molecule is exchanged with the =O group on the other. The original amino acid converts to a keto acid, and the keto acid converts to an amino acid. Transamination in biochemistry is accomplished by enzymes called transaminases or aminotransferases.
