This family consists of several bacterial acetyl xylan esterase proteins. Acetyl xylan esterases are enzymes that hydrolyse the ester linkages of the acetyl groups in position 2 and/or 3 of the xylose moieties of natural acetylated xylan from hardwood. These enzymes are one of the accessory enzymes which are part of the xylanolytic system, together with xylanases, beta-xylosidases, alpha-arabinofuranosidases and methylglucuronidases; these are all required for the complete hydrolysis of xylan [1].

Chains	Enzyme Name	Description	Catalytic Residues
A	cephalosporin-C deacetylase M-CSA #866	Cephalosporin-C deacetylase is an esterase that removes acetyl groups from a number of O-acetylated small substrates, such as acetylated xylose, short xylooligosaccharides and cephalosporin C. It is known not to cleave amide bonds. It is used in the pharmaceutical industry for the chemoenzymatic deacetylation of cephalosporins and the synthesis of novel antibiotics. It is an alpha-beta hydrolase, a member of the carbohydrate esterase 7 family.
