Activation of RidA chaperone function by N-chlorination

Abstract: Escherichia coli RidA is a member of a structurally conserved, yet functionally highly diverse protein family involved in translation inhibition (human), Hsp90-like chaperone activity (fruit fly) and enamine/imine deamination (Salmonella enterica). Here, we show that E. coli RidA modified with HOCl acts as a highly effective chaperone. Although activation of RidA is reversed by treatment with DTT, ascorbic acid, the thioredoxin system and glutathione, it is independent of cysteine modification. Instead, treatm… Show more

“…In addition, protein fragmentation due to halogen transfer as well as cross-linking events have been reported in response to treatment with chloramines (35, 121123). Intriguingly, the E. coli protein RidA was recently identified to specifically sense RCS via reversible N-chlorination, using these modification to turn into a chaperone-active state (124). …”
