Abstract
2pbl, initially annotated as an arylformamidase, was isolated from Silibacter sp. TM1040 and its structure determined by the JCSG. Based on structural, functional and evolutionary analysis, we have further characterised 2pbl. It was found to contain a conserved functional group that is present in a broad range of hydrolases in many taxonomic groups. Specifically, it was found to share similar structural and sequence characteristics of the HSL family of esterases. Probable residues of a catalytic triad were identified as Ser137, His242 and Glu215. Although its specific function is still not known, 2pbl shares a high structural similarity with thermostable HSL esterases. Further experimental characterisation of 2pbl is needed.
