Plasmid- and chromosomal genes involved in Corrin and Adenosyl cobalaimin (B12) uptake, salvage and biosynthesis in Azotobacter chroococcum NCIMB 8003.

A. The region of 16,967 bp from bp 64,013 to 80,225 in plasmid pAcX50f containing a contiguous cluster of genes for corrin synthesis. B. The regions of 12,882 from bp 1,777,467 to 1,789,349; 740,868 to 741,638 and 3,736,258 to 3,738,156 in the chromosome potentially containing genes for corrin and B12 uptake and salvage and the late steps in the synthesis of adenosyl cobalamin.
