strategy of combined site directed mutagenesis and chemicalmodificationcreateschemically modified mutants (CMMs) with greatly broadened substrate specificities. We have previously reported that the CMMs of subtilisinBacilluslentus (SBL) are efficient catalysts for the coupling of both l- and d-amino acids. We now report that these powerful catalysts also allow amide bond formation between a variety
