Hydrolytic enzymes: The marine planctomycete Rhodopirellula baltica DSM 10527 displays high stereo- and enantioselective alkyl sulfatase activity towards (±)-sec-alkyl sulfates with retention of configuration through cleavage of their S[BOND]O bond (see scheme; pathway B), whereas inversion of configuration is observed upon cleavage of the C[BOND]O bond (pathway A).
