Abstract

This entry represents the SGNH hydrolase-type esterase domain, which has a similar fold to flavoproteins, namely a three-layer alpha/beta/alpha structure, where the beta-sheets are composed of five parallel strands. Enzymes containing this domain act as esterases and lipases, but have little sequence homology to true lipases [1, 2]. Proteins containing this type of esterase domain have been found in a variety of hydrolases; those with structural information include an esterase from Streptomyces scabies [3]; the esterase domain of viral haemagglutinin-esterase surface glycoproteins (influenza C virus, coronaviruses and toroviruses) [4]; mammalian acetylhydrolases [5]; fungal rhamnogalacturonan acetylesterase [6]; and the multifunctional enzyme thioesterase I (TAP) from Escherichia coli [7]. SGNH hydrolase-type esterase domains contain unique hydrogen bond network that stabilises their catalytic centres; they usually contain the catalytic triad Ser/Acid/His.
