Abstract
Provided are hydrolases, including lipases, saturases, palmitases and/or stearatases, and polynucleotides encoding them, and methods of making and using these polynucleotides and polypeptides. Further provided are polypeptides, e.g., enzymes, having a hydrolase activity, e.g., lipases, saturases, palmitases and/or stearatases and methods for preparing low saturate or low trans fat oils, such as low saturate or low trans fat animal or vegetable oils, e.g., soy or canola oils.
Claims2
A method for making an enzyme having altered substrate specificity or substrate preference comprising:
- (a) providing a parental hydrolase of SEQ ID NO:2;
- and
- (b) making from one to twelve amino acid residue modifications to the parental hydrolase, wherein at least one of the amino acid residue modifications is V163R, thereby generating an enzyme having at least 95% sequence identity to SEQ ID NO:2 and altered substrate specificity or substrate preference.
