“…However, inhibition of the phe-and his-mutants by CPcys shows the effects were not specific. Similar lack of specificity has been noted by Shigeura et al (9) who found L-O-ethyl threonine, an antagonist to isoleucine in E. co!i, to be counteracted by leucine and valine. Also, Fenster and Anker (10) found incorporation of trifluoroleucine into peptides was inhibited by leucine, isoleucine, and phenylalanine.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
