AslB is predicted to be the anaerobic sulfatase-maturating enzyme (anSME) responsible for the conversion of Ser136 to Calpha-formylglycine (FGly), also known as 3-oxoalanine, in the predicted periplasmic sulfatase AslA (Berteau, 2006). E. coli K-12 cells exhibit mucin-desulfating sulfatase activity but not arylsulfatase activity (Jansen, 1999). anSMEs are also known as Radical SAM superfamily sulfatase-maturases. Rob regulon.
