Alternate requirement for vitamin B12 or methionine in mutants of Pseudomonas denitrificans, a vitamin B12-producing bacterium.
Experiments are described which indicate that Pseudomonas denitrificans, an organism that overproduces vitamin B(12), uses the B(12) pathway exclusively for methionine synthesis.
