We present a case of significant, persistent, and relatively refractory hypotension during general anesthesia in a reasonably healthy 50-year-old man thought to be caused by a direct rennin inhibitor. This case is of particular significance because the medication thought responsible for the hemodynamic abnormalities is a relatively novel antihypertensive agent and remains largely unknown to cli...

Prochymosin is one of the most important aspartic proteinases used as a milk-clotting enzyme in cheese production. In the present investigation we report sequence of cDNA encoding goat ( Capra hircus ) preprochymosin and compare its nucleotide and deduced amino acid sequences with sequences of other ruminants preprochymosin. As bovine prochymosin, the caprine prochymosin cDNA encodes 365 amino ...

Activation of the four separate components of prochymosin (prorennin) at pH 5.0 demonstrated that each zymogen was the precursor to an electrophoretically distinct chymosin (rennin). When the increase in milk-clotting activity with time was analysed, the mechanism of activation of unfractionated prochymosin, individual prochymosin components, and a mixture of the prochymosin fractions at pH 5.0...
