Structure of closed form Monoacylglycerol lipase (MGL) isolated from Bacillus sp. H257 (bMGL) is published by Tsurumura et al. and will be available soon (4LHE). Novel human BChE variants (Y332S, D340H, and Y332S/D340H) were identified by Dwyer et al. with an increased resistance to nerve agent and retained robust catalytic efficiency. Crystal structure of a C4-C4 SN3 tributyrin phodphonate inhibited Esterase B from Lactobacillus Rhamnosis is available (4PO3) and will soon be published by Bennett et al.
