Fig. 2From: Role of protein repair enzymes in oxidative stress survival and virulence of SalmonellaConversion of Asp to iso-Asp and their repair by PIMT: Under stress Asp or Asn residues in the proteins convert into succinimide. Succinimide spontaneously convert into normal Asp or abnormal iso-Asp residues in a ratio of 1:3. PIMT catalyzes conversion of iso-Asp residues into succinimide. Few cycles of PIMT-mediated repair converts all iso-Asp to AspBack to article page
