UniProtKB description:  TesA is a multifunctional esterase that can act as a thioesterase, lysophospholipase and protease (PubMed:10423542, PubMed:1864840, PubMed:238979, PubMed:4554913, PubMed:4945109, PubMed:791643, PubMed:8098033, PubMed:8132479, PubMed:8432696, PubMed:9070299). TesA functions as a thioesterase specific for fatty acyl thioesters of greater than ten carbons, with highest activity on palmitoyl-CoA, cis-vaccenoyl-CoA and palmitoleoyl-CoA (PubMed:10423542, PubMed:4554913, PubMed:8098033, PubMed:8132479, PubMed:9070299). TesA also possesses an arylesterase activity towards short acyl-chain aromatic esters such as alpha-naphthyl acetate, alpha-naphthyl butyrate, benzyl acetate and phenyl acetate (PubMed:9070299). Also able to hydrolyze short acyl-chain triacylglycerols such as triacetin and tributyrin, and p-nitrophenyl esters such as p-nitrophenyl hexanoate and p-nitrophenyl butyrate (PubMed:9070299). The protease activity is mainly active on small peptides (PubMed:8432696, PubMed:9070299). TesA is also able to hydrolyze p-nitrophenyl esters of N-substituted amino acids such as N-benzyloxycarbonyl-L-Phe-p-nitrophenyl ester (Z-L-Phe-ONp) and N-benzyloxycarbonyl-L-Tyr-p-nitrophenyl ester (Z-L-Tyr-ONp), however it is unable to hydrolyze N-acetyl-L-Phe ethyl ester and its Tyr analog (PubMed:10423542, PubMed:791643, PubMed:8432696). TesA also hydrolyzes N-benzyloxycarbonyl-L-Phe beta-nitrophenyl ester (Cbz-Phe-ONap) and N-acetyl-DL-Phe-2-naphthyl ester (chymotrypsin-like specificity) (PubMed:4945109, PubMed:8432696). Shows a slow proteolytic activity against denatured casein (PubMed:4945109). The lysophospholipase activity of TesA is able to hydrolyze 1-palmitoyl-sn-glycero-3-phosphocholine, 1-acyl-sn-glycero-3-phosphoglycerol, 1- and 2-acyl-sn-glycero-3-phosphoethanolamine (PubMed:10423542, PubMed:1864840, PubMed:238979).
