Structural insight into a CE15 esterase from the marine bacterial metagenome is published by De Santi et al. and structure is available (6EHN) Crystal Structures of D14 and DAD2 (strigolactone receptors) bound to N-phenylanthranilic acid derivatives are available (6AP6, 6AP7, 6AP8) and published by Hamiaux et al. Structure of the loading/condensing region of the cercosporin fungal non-reducing polyketide synthase (Only the c-terminal thioesterase module is an alpha/beta hydrolase) is available (6FIK) and is published by Herbst et al.
