Abstract:
1. A method for enzymatic treatment of a chlorophyll- or chlorophyll derivative-containing oil comprising the following steps: a) providing a chlorophyll or chlorophyll derivative containing oil b) providing at least one polypeptide having a chlorophyllase activity or a chlorophyll catabolic enzyme activity; and c) reacting the composition of step a) with the polypeptide of step b) under conditions wherein the polypeptide can catalyze a chlorophyll-modifying reaction, wherein the polypeptide: (i) has at least 95%, 96%, 97%, 98%, 99%, or more, or has 100% sequence identity to SEQ ID NO:10 and the polypeptide retains chlorophyllase or chlorophyllase catabolic activity; or (ii) is encoded by a nucleic acid sequence having at least 95%, 96%, 97%, 98%, 99%, or more, or has 100% sequence identity to SEQ ID NO:9; and the polypeptide retains chlorophyllase or chlorophyllase catabolic activity; or (iii) is the polypeptide of (i) or (ii) but lacking its homologous signal sequence or prepro sequence; or (iv) is the polypeptide of (i), (ii), or (iii), further comprising a heterologous sequence; or (v) is the polypeptide of (i), (ii), (iii), or (iv), further comprising a targeting sequence, an N-terminal identification peptide or a stability or simplified purification peptide sequence.
