In certain embodiments, the present invention comprises compositions and methods useful in the generation of acyl amino acids. In certain embodiments, the present invention provides an engineered polypeptide comprising a peptide synthetase domain; in some such embodiments, the engineered polypeptide comprises only a single peptide synthetase domain. In some embodiments, the present invention provides an engineered peptide synthetase that is substantially free of a thioesterase domain, and/or a reductase domain. In certain embodiments, the present invention provides an acyl amino acid composition comprising a plurality of different forms of an acyl amino acid. In some such compositions, substantially all of the acyl amino acids within the composition contain the same amino acid moiety and differ with respect to acyl moiety. We also described populations where the fatty acid si for example 95% one length (C14, myristic). |
