标题 :Recombinant polynucleotide involved in lactone synthesis and process for synthesis of lactones thereof
发明人：GUPTA VIDYA SHRIKANT; DESHPANDE ASHISH BALWANT; OAK PRANJALI SUDHIR; GIRI ASHOK PRABHAKAR
权利人:COUNCIL SCIENT IND RES
摘要:The present invention provides the polynucleotide encoding enzyme involved in lactone synthesis and a process for synthesis of lactones using said polynucleotides. The invention also provides recombinant plasmid expression vector comprising said polynucleotide sequence. The recombinant protein encoded by said polynucleotides leads to synthesis of lactones having flavour peculiar to Alphonso mangoes.

权利人:LEWIS II JOSEPH ABERNATHY; DINARDO JOSEPH C; PCR TECH HOLDINGS LC
摘要:The present invention relates to cosmetic or dermatological compositions containing PQQ or its esters, methods of treating or promoting skin changes by topical application of these compositions, and methods of synthesis of PQQ esters. The PQQ ester-containing compositions of the present invention are unexpectedly effective in treating skin, particularly with respect to skin tolerance. When included in a topical composition, the PQQ esters of the present invention have an antioxidant effect that is useful in treating a skin change.
