Escherichia coli K-12 substr. MG1655 Protein: universal stress protein UP12



Gene: uspG Accession Numbers: G6334 (EcoCyc), b0607, ECK0601

Synonyms: UP12, yzzU, ybdQ

Regulation Summary Diagram: ?

Subunit composition of universal stress protein UP12 = [UspG]2
         universal stress protein UP12 = UspG

Summary:
UspG belongs to the class II (UspF/G) subfamily of universal stress proteins [Kvint03]. UspG possesses intrinsic autophosphorylation and autoadenylation activity; the C-terminal domain of UspG is important for these activities and required for dimerization [Weber06]. UspG binds to GroEL [Bochkareva02].

A uspG mutant exhibits a defect in resumption of growth after reaching stationary phase and exhibits increased sensitivity to carbonyl cyanide m-chlorophenyl hydrazone (CCCP, a respiratory chain uncoupler), compared to wild type [Bochkareva02]. A uspG mutant is impaired in cell aggregation and fimbria-dependent adhesion [Nachin05]. A uspF uspG double mutant is more sensitive to streptonigrin, indicating increased availability of intracellular free iron [Nachin05].

UspG abundance is increased in response to stresses including heat, stationary phase, carbon or phosphate starvation, and CCCP treatment [Bochkareva02].

UP12: "unknown protein" [Bochkareva02].
