What's a GeneRIF?

A pH-dependent kinetic study shows that both cross-linked and un-cross-linked CDO are active but the optimal pH decreases with the presence of the cross-link.
Title: The Cys-Tyr cross-link of cysteine dioxygenase changes the optimal pH of the reaction without a structural change.
redox switch commits CDO towards either formation of the Cys93-Tyr157 crosslink or oxidation of the cysteine substrate
Title: Shifting redox states of the iron center partitions CDO between crosslink formation or cysteine oxidation.
Data suggest that biocatalysis by cysteine dioxygenase (CDO1) involves formation of persulfides of both cysteine and 3-mercaptopropionic acid under reducing conditions; these persulfides are stabilized by iron in active site of CDO1.

Correlating crosslink formation with enzymatic activity in cysteine dioxygenase.
Title: Correlating crosslink formation with enzymatic activity in cysteine dioxygenase.
Iron dissociation from the CDO active site exhibits an extremely slow dissociation rate constant, illustrating the stability of the resting state CDO; dioxygenase activity is directly proportional to the concentration of iron.

The regulation of Cysteine-Tyrosine cofactor formation in CDO by ambient cysteine levels represents an unusual form of substrate-mediated feed-forward activation of enzyme activity with important physiological consequences.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
