Comment

This family was extracted from the previous Carboxylesterase COesterase family. Carboxylesterase, type B (COesterase) is very successful in fungi. Grouped with Lipase_3 in Family Fungal lipases in scop database. This family corresponds to the Carbohydrate Esterase family CE10 in CAZy - Carbohydrate-Active enZYmes database (CE_10) LED_Database abH03 abH02. The presence of a water/lipid interface dramatically enhances the hydrolytic activity of lipases. The activation is associated with a conformational change (Grochulski 1993, Grochulski 1994, Schrag 1993). The Ser-His-Asp/Glu catalytic triad is occluded by a polypeptide flap (lid) and is not exposed to the solvent until the lid is open. A protein of this family lacking the catalytic serine is a dirigent protein which controls the stereoselectivity of multicopper oxidase(VdtB)-catalyzed phenol coupling in viriditoxin biosynthesis (Hu et al. 2019)
