Research Papers that Mention the Interaction
“Among the correlations between a-cs differences the negative relationship between lactate and alanine and the negative correlation between cystine-cysteine and leucine, isoleucine and glutamine is significant.”
Amino acid metabolism in the heart muscle in subjects with ischaemic heart disease at rest and during pacing.“At position 113, substitution of leucine for isoleucine had little effect, but activity was reduced 15-fold by substitution with cysteine.”
Cassette mutagenesis of a potential substrate recognition region of cytochrome P450 2C2.“The burgeoning cysteine pool is itself hazardous, as cysteine promotes the formation of reactive oxygen species, triggers sulfide production and competitively inhibits a key enzyme in the isoleucine biosynthetic pathway.”
Cystine import is a valuable but risky process whose hazards Escherichia coli minimizes by inducing a cysteine exporter“The toxic effect of cysteine was reduced by leucine itself, as well as by a mixture of leucine, isoleucine , valine and threonine.”
“These results suggest a relationship between the growth-inhibitory effects of cysteine and other sulfur compounds and the inhibition of isoleucine synthesis at the level of threonine deaminase.”
“The transport activity for labeled isoleucine in the transport mutant and wild-type strains was inhibited by unlabeled L-alanine, L-cysteine , L-isoleucine, L-leucine, L-methionine, L-threonine, and L-valine.”
“ Cysteine promotes growth, and serine, ornithine and isoleucine act synergistically with it.”
