An Mg2+ and ATP dependent beta-lactam synthetase (BLS) catalyses formation of a beta-lactam ring during the biosynthesis of clavulanic acid, an important beta-lactamase inhibitor. An epimeric mixture of a 2-methylated derivative of the natural BLS substrate N2-(2-carboxyethyl)-L-arginine was synthesised and

Streptomyces clavuligerus beta-lactam synthetase (beta-LS) was recently demonstrated to catalyze an early step in clavulanic acid biosynthesis, the ATP/Mg(2+)-dependent intramolecular closure of the beta-amino acid N(2)-(carboxyethyl)-L-arginine (CEA) to the monocyclic beta-lactam deoxyguanidinoproclavaminic acid (DGPC). Here we investigate the steady-state kinetic

Agrobacterium tumefaciens is well known to cause crown gall tumours at plant wound sites and to benefit from this plant association by obtaining nutrients called opines that are produced by these tumours. Tumourigenesis requires expression of the vir regulon in

We constructed a gene library of a nopaline-type Ti plasmid (called pTi-SAKURA) which was newly isolated from Agrobacterium tumefaciens MAFF301001 of a Japanese cherry tree. The partial sequencing data, which were distributed over the entire plasmid genome, made it possible

The vir regions of octopine-type and nopaline-type Ti plasmids direct the transfer of oncogenic T-DNA from Agrobacterium tumefaciens to the nuclei of host plant cells. Previous studies indicate that at least two genetic loci at the left ends of these
