Gostatin
Gostatin is an inhibitor of aspartate aminotransferase (GOT). Gostatin is found in Streptomyces sumanensis nov. sp. NK-23. Gostatin has a strong inhibitory effect on pig heart GOT, a weak inhibitory effect on wheat germ GOT and GPT, and no significant effect on glutamate dehydrogenase and glutamine synthetase. The inhibitory mechanism of gostatin is similar to substrate competitive inhibition, and aspartate has a protective effect on its inhibitory effect. Gostatin can be used to study the catalytic mechanism of GOT and its role in nitrogen metabolism[1].
