MetaCyc Enzyme: peptidyl-prolyl cis-trans isomerase C (rotamase C)

Gene: ppiC Accession Numbers: EG12352 (MetaCyc), b3775, ECK3767

Synonyms: parvA, Par10, parvulin

Species: Escherichia coli K-12 substr. MG1655

ppiC encodes a peptidyl-prolyl cis-trans isomerase, parvulin, which defines a new family of PPIases [Rahfeld94a, Rahfeld94]. Unlike other peptidyl-prolyl cis-trans isomerases, the enzymatic activity of parvulin is not inhibited by FK506 or cyclosporin A [Rahfeld94a]. The natural compound juglone specifically and irreversibly inactivates parvulin by covalent modification [Hennig98]. The stereospecificity of the enzyme has been studied [Schiene98], and a solution structure of PpiC has been determined [Kuhlewein04].

AhpC has been identified as a specific interaction partner of PpiC [Malesevic10].

A ppiC mutant is more sensitive to oxidative stress than wild type [Malesevic10].

Resequencing of multiple isolates of the MG1655 strain has identified several genetic variations compared to the reference sequence, including a single-nucleotide polymorphism in the yifO-ppiC intergenic region [Freddolino12]. This EcoliWiki page summarizes these sequence differences.

PpiC prefers amino acid residues with hydrophobic side chains such as leucine and phenylalanine in the P1 position of the peptide substrate [Rahfeld94a] and shows only a slight preference for nonpolar residues following proline [Schmidpeter11].

Inhibitors (Irreversible): juglone [Hennig98]
