Subunit composition of enamine/imine deaminase, redox regulated chaperone = [RidA]3
         enamine/imine deaminase, redox regulated chaperone = RidA


In E. coli K-12 the conserved protein RidA has been characterised as a redox-regulated chaperone that is activated in response to hypochlorous acid (HOCl) stress. RidA activation is mediated by chlorination; RidA activation is accompanied by loss of free amino groups and increased hydrophobicity. Chlorination of RidA is reversible; N-chlorinated RidA is reduced by dithiothreitol and ascorbic acid in vitro and by glutathione and thioredoxin in vivo [Muller14].

Purified RidA is active as an enamine/imine deaminase in vitro [Lindemann13].

HOCl treated RidA and monochloramine (a HOCl derived chloramine) treated RidA both prevent aggregation of denatured citrate synthase in vitro [Muller14].

Deletion of ridA in an E. coli BL21 strain results in increased sensitivity to HOCl; lack of ridA may be lethal in E. coli K-12 MC4100 [Muller14].

Purified, crystallised RidA is homotrimeric; the structure contains a covalent modification on the Sγ of Cys107 [Volz99]. RidA is oxidised at Cys107 by peroxynitrite treatment; purified RidA accelerates the IlvA dependent formation of 2-ketobutyrate from threonine in vitro; when treated with peroxynitrite this effect is eliminated; a RidA(C107S) substitution mutant retains the activating effect but can no longer be inactivated by peroxynitrite treatment [Lindemann13].

A RidA(C107S) substitution mutant retains chaperone activity after HOCl treatment [Muller14].

RidA can be modified with fatty acid metabolites in vitro; based on the analysis of a C107S mutant, the modification may occur at C107 [Rangan10].
