"Protease I" of Escherichia coli functions as a thioesterase in vivo.

PMCID: PMC205273  PMID: 8132479

Abstract

Escherichia coli protease I is assayed as an esterase active with certain synthetic model chymotrypsin substrates. However, the gene encoding protease I has the same DNA sequence and genomic location as tesA, a gene that encodes E. coli thioesterase I. We report that both hydrolase activities utilize the same active site and demonstrate that the protein functions as a thioesterase in vivo.
