Reduction of Non-Steroidal Anti-Inflammatory Drug Induced Gastric Damage in the Rat by Soluble Pepstgastric ulceration often arises as a complication of trauma or surgery. The drugs used to treat peptic ulcers either inhibit acid secretion (e.g. H2-antagonists) or stimulate gastric defences (e.g. prostaglandins, bismuth salts). Neither therapy is ideal because of side effects and problems with rec

Amino Acid Sequence of Lamb Preprochymosin and its Comparison to Other Chymosinsf two calf chymosin forms (A and B) are known.. The only difference in their structures is at position 302 (preprochymosin numbering). More recently, other forms of calf chymosin were also found and sequenced.. Calf chymosin has been cloned in many laboratories using different expression vector/host

Quantum-Chemical Study of the Catalytic Mechanism of Aspartic Proteinasesxample references 2-4) clearly show that two aspartic acid residues Asp. and Asp. (porcine pepsin sequence) are involved in catalysis. These residues are bound to each other by a hydrogen bond and possess different acid dissociation constants.(pK.) (for porcine pepsin, 1.5 and 4.7, respectively.. Th

Characteristics and Composition of Pepsins from Atlantic Codificant evolutionary gap between fish and mammalian pepsins. A comparative evaluation of the results obtained indicate that fish pepsins may constitute an intermediate stage in a genetic evolution from cathepsin D to mammalian pepsin.
