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).
在某些实施方案中,本发明包括用于生成酰基氨基酸的组合物和方法。在某些实施方案中,本发明提供了一种包含肽合成酶结构域的工程多肽;在某些这样的实施方案中,工程多肽仅包含单个肽合成酶结构域。在某些实施方案中,本发明提供了一种基本上不含硫酯酶结构域和/或还原酶结构域的工程肽合成酶。在某些实施方案中,本发明提供了一种包含多种不同形式酰基氨基酸的酰基氨基酸组合物。在某些此类组合物中,组合物中基本上所有的酰基氨基酸都含有相同的氨基酸分子,并在酰基分子方面有所不同。我们还描述了脂肪酸si例如长度为95%(C14,肉豆蔻酸)的群体。
