Abstract excerpt
Catabolic mannopine (MOP) cyclase encoded by Ti or Ri plasmids lactonizes MOP to agropine (AGR). The gene of the octopine-type Ti plasmid pTi15955 encoding the catabolic MOP cyclase enzyme previously was localized to a 1.6-kb segment within a cosmid clone, pYDH208. A subclone containing only this region complemented the AGR catabolism-negative phenotype conferred by a derivative of the octopine-type plasmid...
