标 题 :Synthesis of glufosinate using an amidase-based process
发明人：ZIMMERMANN GUNTHER; POTT MORITZ STEFAN
权利人:BASF SE
摘要:The present invention relates to a method of preparing glufosinate, comprising the steps of hydrolysing an N-carbamoyl glufosinate amide with an Amidase enzyme to form an N- carbamoyl amino acid compound followed by cleaving off the carbamoyl moiety of said N- carbamoyl amino acid compound.

摘要:The present invention relates to a process for the isolation and characterisation of a gene-enzyme system for the inactivation of the herbicide phenmedipham. The enzyme is a carbamate hydrolase from Arthrobacter oxidans which is responsible for the hydrolytic cleavage of the -OOC-N linkage between the two phenyl nuclei of phenmedipham. The process includes the detection of carbamate hydrolase, the identification of the amino-acid sequence of two BrCN-cleaved peptides of carbamate hydrolase, the synthesis of oligonucleotides for the specific detection of the carbamate hydrolase sequence by hybridisation, and the identification of the coding region, the cloning and the determination of the nucleotide sequence of the carbamate hydrolase gene from Arthrobacter oxidans.

摘要:An object of the present invention is to identify an enzyme having activity of synthesizing dihydrotentoxin that is a tentoxin precursor and an enzyme having activity of synthesizing tentoxin using dihydrotentoxin as a substrate. The present invention concerns a tentoxin synthesis-related gene encoding a protein comprising the amino acid sequence of SEQ ID NO: 16 and having activity of nonribosomal peptide synthesis of dihydrotentoxin and a tentoxin synthesis-related gene encoding a protein comprising the amino acid sequence of SEQ ID NO: 18 and having activity of converting dihydrotentoxin to tentoxin.
