Analysis of the growth of recombination-deficient strains of Escherichia coli K-12.

abstract：:The mocC gene encoded by the octopine/mannityl opine-type Ti plasmid pTi15955 is related at the nucleotide sequence level to mas1' encoded by the T region of this plasmid. While Mas1 is required for the synthesis of mannopine (MOP) by crown gall tumor cells, MocC is essential for the utilization of MOP by Agrobacteriu...
