标题:Enzymatic synthesis of odilorhabdin and related peptides/proteins comprising non-standard amino acid residues
权利人:MAX PLANCK GESELLSCHAFT
摘要:The present invention relates to a novel method of preparing a non-standard amino acid or a peptide/protein comprising a non-standard amino acid residue, as appropriate, wherein said amino acid residue is selected from 2,4-diamino-3-hydroxybutyrate, L-5-hydroxylysine, L-3-hydroxyarginine, 2,3-didehydroarginine by using enzymatic transformations. Accordingly, the present invention further relates to a method of preparing a peptide/protein comprising one or more non-standard amino acids selected from 2,4-diamino-3-hydroxybutyrate, L-5-hydroxylysine, L-3-hydroxyarginine and 2,3-didehydroarginine. The methods of the present invention are particularly useful in enzyme-assisted preparation of odilorhabdins and their derivatives. The present invention further relates to a polypeptide having 2,4-diaminobutyrate-3-hydroxylase activity and its use for catalyzing a hydroxylation at position 3 of 2,4-diaminobutyrate, to a polypeptide having having L-arginine 3-hydroxylase activity and its use for catalyzing a hydroxylation at position 5 of L-lysine, to a polypeptide having L-arginine 3-hydroxylase activity and its use for for catalyzing a hydroxylation at position 3 of L-arginine, and to a polypeptide having a deacylase activity, which is preferably capable of removing fatty acyl from the N-terminus of an odilorhabdin, and its use for catalyzing a deacylation, preferably for removing a fatty acyl from the N-terminus of an odilorhabdin.

标 题:0-2-Isocephem-4-carboxylic acid derivatives as antibacterial agents
发明人:DOUGLAS JAMES L; HORNING DONALD E; MORRIS LEESON R
权利人:BRISTOL MYERS CO
摘要:There is described the stereoselective total synthesis of novel DELTA 2,3-1,4-morpholine-2-carboxylic acids possessing a fused beta -lactam ring in the 1,6-position and carrying a substituent cis to carbon 5 in the 7-position of the fused ring system represented by the general formula I wherein X is acylamino and Z represents optionally substituted C1-C6 alkyl, aryl or aralkyl. Also included in the invention are compounds of the above formula in which the carboxyl group at the 2-position is protected as by an easily cleavable ester group and salts of both the free acids and carboxyl-protected compounds. The compounds are potent antibacterial agents.

标题:Microorganisms and methods for the production of butadiene using acetyl-coA
发明人:PHARKYA PRITI; BURGARD ANTHONY P; BURK MARK J
权利人:GENOMATICA INC
摘要:The invention provides non-naturally occurring microbial organisms containing butadiene or 2,4-pentadienoate pathways comprising at least one exogenous nucleic acid encoding a butadiene or 2,4-pentadienoate pathway enzyme expressed in a sufficient amount to produce butadiene or 2,4-pentadienoate. The organism can further contain a hydrogen synthesis pathway. The invention additionally provides methods of using such microbial organisms to produce butadiene or 2,4-pentadienoate by culturing a non-naturally occurring microbial organism containing butadiene or 2,4-pentadienoate pathways as described herein under conditions and for a sufficient period of time to produce butadiene or 2,4-pentadienoate. Hydrogen can be produced together with the production of butadiene or 2,4-pentadienoate.
