The present invention relates to a polypeptide having phospholipase C activity, selected from the group consisting of
i. a polypeptide comprising a mature polypeptide sequence of SEQ ID NO: 2;
ii. a polypeptide that has least 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98% or 99% identity to the mature polypeptide sequence of SEQ ID NO: 2;
iii. a polypeptide encoded by a nucleic acid that hybridizes under medium stringency, preferably under high stringency conditions to the complementary strand of the mature polypeptide coding sequence of SEQ ID NO:1;
iv. a polypeptide encoded by a nucleic acid that has at least 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or 100% identity to the mature polypeptide coding sequence of SEQ ID NO: 1.
A process for degumming a vegetable oil comprising contacting a vegetable oil comprising phospholipids with a polypeptide having phospholipase C activity of the invention or a composition of the invention, wherein phospholipids are hydrolyzed into diacylglycerol and phosphate ester and/or phosphate, separating the phosphate ester and/or phosphate from the vegetable oil wherein a degummed vegetable oil is obtained.
