Enzyme Information

3.1.1.72
Acetylxylan esterase.
based on mapping to UniProt Q9WXT2
Deacetylation of xylans and xylo-oligosaccharides.
-!- Catalyzes the hydrolysis of acetyl groups from polymeric xylan, acetylated xylose, acetylated glucose, alpha-napthyl acetate, p-nitrophenyl acetate but not from triacetylglycerol. -!- Does not act on acetylated mannan or pectin.
3.1.1.41
Cephalosporin-C deacetylase.
based on mapping to UniProt Q9WXT2
Cephalosporin C + H(2)O = deacetylcephalosporin C + acetate.
-!- Hydrolyzes the acetyl ester bond on the 10-position of the antibiotic cephalosporin C.
