摘要:
This invention relates to isolated polynucleotides encoding chlorophyllases. The invention also relates to the construction of recombinant DNA fragments comprising all or a portion of the isolated chlorophyllase-encoding polynucleotides, in sense or antisense orientation, wherein expression of the recombinant DNA fragment results in production of altered levels of chlorophyllase in a transformed host cell.
摘要:
The present invention relates to isolated polypeptides having chlorophyllase activity, and polynucleotides encoding the polypeptides. The invention further relates to the use of such polypeptides in detergent and/or in cleaning processes. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the polynucleotides as well as methods of producing the polypeptides.

摘要:
Dried fruits are treated by contacting and incubating them with a glycerol solution containing a carbohydrase enzyme in an amount of 0.05 to 0.5 parts enzyme by weight per 100 parts fruit at a temperature of from 40.degree. C. to 60.degree. C. for a time sufficient so that the fruit absorbs at least 10% by weight glycerol. The carbohydrase enzyme is inactivated and the incubated fruit is dried so that the fruit has a water activity of from 0.25 to 0.40.
摘要:
The present invention relates to a process for treating an oil comprising a chlorophyll substrate, the process comprising contacting the oil with a polypeptide having decolorase activity or a composition comprising the polypeptide, wherein the polypeptide is selected from the group consisting of:
a. a polypeptide which has at least 80% identity to amino acids 1 to 318 of SEQ ID NO: 1; and, b. a polypeptide encoded by a nucleic acid sequence that has at least 80% identity to the nucleic acid sequence of SEQ ID NO: 2.
