Structure of a novel esterase from the GTSAG motif subfamily of bacterial Hormone-Sensitive Lipase (HSL) family is available (4Q05) and published by Li et al.. Accordingly a new family was introduced: (GTSAGmotif). A paper by McMahon et al. shows that Comparative gene identification 58 (CGI-58)/Alpha Beta Hydrolase Domain 5 (ABHD5) (human-ABHD5) lacks lysophosphatidic acid acyltransferase activity. Parkkari et al. show that triterpenoids are reversible inhibitors of alpha/beta-hydrolase Domain Containing 12 (ABHD12)
