...catalysts in all the chemical reactions necessary for life. The group's latest interest has been an enzyme called subtilisin, which is found in ordinary soil bacteria. As they investigated subtilisin's complex structure, the scientists realized that it had a curious similarity to another enzyme, chymotrypsin, common to all vertebrates, including man. While the overall molecular architecture of the two enzymes is quite different, they both have three identical groups of amino acids that form what Kraut calls their "business ends." It is at these spots that the chemicals involved in vital reactions are brought together...
...varies with the patient's health. He attributed this to the relative strength of two enzyme inhibitors. These two inhibitors are mysterious, complex substances, not yet isolated and still nameless. They serve as policemen, regulating the action of the two enzymes: rennin (found mainly in the stomach) and chymotrypsin (in the pancreas). Both the enzymes are ferments which curdle milk. Their inhibitors circulate in the bloodstream...
...presence of cancers, West found, the chymotrypsin inhibitor is greatly multiplied. As soon as a cancer patient responds favorably to treatment, the normal proportion (with the rennin inhibitor more abundant) is restored. Sometimes, West reported this week in the Annals of Western Medicine and Surgery, his test will give the first indication that a patient needs fresh treatment (for example, X rays) if recovery is to continue...
