PROTEASE Bacterial neutral proteases are active in a narrow pH range (pH 5 to 8) and have relatively low thermotolerance. Due to their intermediate rate of reaction, neutral proteases generate less bitterness in hydrolyzed food proteins than do the animal proteinases and hence are valuable for use in the food industry. Neutrase, a neutral protease, is insensitive to the natural plant proteinase inhibitors and is therefore useful in the brewing industry. The bacterial neutral proteases are characterized by their high affinity for hydrophobic amino acid pairs.

- in the gastric mucosa. The low pH (~2) of the gastric juice aids protein digestion in a couple of ways. First, the low pH denatures the tertiary structures of ingested protein, making them easier to digest enzymatically. Secondly, the low pH is required for the activation of pepsin. Pepsin is produced by chief cells of the gastric mucosa in an inactive (zymogenic) form called pepsinogen. Pepsinogen is inactive when released in the gastric pits, but once it diffuses into the lumen of the stomach the acidic conditions enable it to have a weak proteolytic activity (Fig 11.3). Pepsinogen can digest some Enzyme Activity pH

Animal vs. Plant Protein That is, ‘substrate’ amino acids derived from animal based proteins are more readily available for our own protein synthesizing reactions which allows them to operate at full tilt. Plant proteins are somewhat compromised by their limitation of one or more amino acids. When we restore the relatively deficient amino acid in a plant protein, we get a response rate equivalent to animal proteins. My own lab produced experimental data to support this view–and of course, similar observations of years past in other laboratories can also be interpreted in this way.

What are Protease Inhibitors and How Do They Work? The Protein Man Says: Protease inhibitors are chemical compounds used to protect protein samples from the digestive function of proteases which is triggered during the isolation procedure. As such, they are used to preserve cell lysates and protein samples from imminent natural degradation.

- The quantities of enzymes produced vary depending on the bacterial species and the culture conditions (e.g., nutrients, temperature, and pH) and growth rate. Hydrolytic enzymes such as. proteases, amylases, and cellulases, etc. are produced in the range of milligrams per liter to grams per liter. 10.o enzymes break down any molecule or just specific ones and how specific do they get: (Above). The specificity of an enzyme for it's substrate is generally a function of the enzyme's active site or binding site. The structure of the protein determines the range of substrates or keys that can fit into the lock.

- Each decarboxylase enzyme produced by an organism is specific to the amino acid on which it acts. Therefore, we test the ability of organisms to produce arginine decarboxylase, lysine decarboxylase, and ornithine decarboxylase using three different but very similar media.ecarboxylase broth contains nutrients, dextrose (a fermentable carbohydrate), pyridoxal (an enzyme cofactor for decarboxylase), and the pH indicators bromcresol purple and cresol red. Bromcresol purple turns purple at an alkaline pH and turns yellow at an acidic pH.

Plant nutrients functions, optimal- and off-levels Uptake of K is greatly inhibited in cucumber seedlings (cv. Saticoy) fed by nutrient solution containing NH4+ + NO3- (2:1 ratio), compared to NO3- only (Figure 3.1). Moreover, this study also established that the ammonium ion doubles the chloride influx into roots, and this inhibits growth of the seedlings.

Structural Biochemistry/Enzyme Regulation/Proteolytic activation For instance, digestive enzymes which hydrolyze proteins are made as zymogens in the stomach and pancreas, in which pepsinogen is the inactive precursor (zymogen) and pepsin is the activated form of the enzyme. Another example is seen in blood clotting which is carried out by a cascade of proteolytic activations.ommon uses in Biological Systems [edit]. Digestive enzymes are activated in the stomach and pancreas using this methodology. They are synthesized first as zymogens. Pepsinogen is the inactive protein which is initially transcribed.
