AppppA-binding protein E89 is the Escherichia coli heat shock protein ClpB.

Journal of bacteriology - 1 Apr 1993

Fuge E K, Farr S B

Abstract excerpt

Dinucleotide AppppA (5',5'''-P1,P4-diadenosine tetraphosphate) is rapidly synthesized in Escherichia coli cells during heat shock. apaH mutants lack AppppN hydrolase activity and, therefore, contain constitutively levels of AppppA, which affect several cellular processes. However, the precise role of AppppA remains undetermined. Photo-crosslinking experiments with radioactively labelled azido-AppppA have shown...
