Rab (G-protein) Rab proteins are peripheral membrane proteins, anchored to a membrane via a lipid group covalently linked to an amino acid. Specifically, Rabs are anchored via prenyl groups on two cysteines in the C-terminus.ecause Rab proteins are anchored to the membrane through a flexible C-terminal region, they can be thought of as a 'balloon on a string'. Like other GTPases, Rabs switch between two conformations, an inactive form bound to GDP (guanosine diphosphate), and an active form bound to GTP (guanosine triphosphate).

- Rabies virions contain four major polypeptides of different molecular size. One of them constitutes the protein moiety of the viral nucleocapsid, which is a single-stranded helical protein, whereas the remaining three are considered to be components of the viral envelope (Albertini et al., 1997) .

- Based on the physical and chemical properties of R groups, the 20 amino acids of proteins may be classified as follows. 1. Acidic: including aspartic acid (aspartate) and glutamatic acid (glutamate). In a neutral solution, the R group of an acidic amino acid may lose a proton and become negatively charged. 2. Basic: including lysine, arginine and histidine. In a neutral solution, the R group of a basic amino acid may gain a proton and become positively charged. Interaction between positive and negative R groups may form a salt bridge, which is an important stabilizing force in proteins. 3. Aromatic: including tyrosine, tryptophan and phenylalanine. Their R groups contain an aromatic ring. 4.

Proteins While many of the proteins are structural proteins, many are regulatory proteins called enzymes. They contain carbon, hydrogen, and oxygen like the carbohydrates and lipids, but they also contain nitrogen and often sulfur and phosphorus. Protein molecules are often very large and are made up of hundreds to thousands of amino acid units.

- From Wikipedia, the free encyclopedia. A ribosomal binding site (RBS) is a sequence on mRNA that is bound by the ribosome when initiating protein translation. In eukaryotes it is the 5' cap of the messenger RNA, in prokaryotes it is a region called the Shine-Dalgarno sequence 6-7 nucleotides upstream of a start codon.Additionally viruses can have internal ribosome entry sites (IRES) within an mRNA transcript.n eukaryotes it is the 5' cap of the messenger RNA, in prokaryotes it is a region called the Shine-Dalgarno sequence 6-7 nucleotides upstream of a start codon.

What are Recombinant Proteins? Recombinant DNA (rDNA) molecules are DNA sequences that is a consequence of molecular cloning (used to assemble recombinant DNA molecules) to assemble the genetic material from various sources, making sequences that cannot be predicted in biological organisms.he term recombinant DNA means that two segments of DNA in a plasmid. Plasmids are those which generally occur in bacteria. Once a recombinant DNA is inserted into bacteria, these bacteria will make protein based on this recombinant DNA.

Protein Electrophoresis - Serum Serum proteins are classified as albumin or globulins. Albumin is the protein of highest concentration in the serum. It carries many small molecules, but is also important for keeping fluid from leaking out from the blood vessels into the tissues. Globulins are divided into alpha-1, alpha-2, beta, and gamma globulins.

Role of Rab GTPases in Membrane Traffic and Cell Physiology Unlike Rab GAP proteins, there are, to date, no clear motifs that define Rab GEF proteins. However, the structures of several GEF proteins indicate that they directly insert into, or indirectly alter, the Rab nucleotide or magnesium-binding site to cause displacement of the bound nucleotide (38).ab proteins are also involved in movement of organelles. Yeast cells utilize different pathways, some of which share factors in common, to ensure that the daughter cell acquires the full complement of organelles necessary for survival.

DNA-binding protein DNA-binding proteins are proteins that are composed of DNA-binding domains and thus have a specific or general affinity for either single or double stranded DNA. Sequence-specific DNA-binding proteins generally interact with the major groove of B-DNA, because it exposes more functional groups that identify a base pair.However there are some known minor groove DNA-binding ligands such as netropsin, distamycin, Hoechst 33258, pentamidine, DAPI and others.he specificity of these transcription factors' interactions with DNA come from the proteins making multiple contacts to the edges of the DNA bases, allowing them to read the DNA sequence. Most of these base-interactions are made in the major groove, where the bases are most accessible.
