Bacterial differentiation, development, and disease: mechanisms for survival.

abstract：:While there is an extensive database of genes encoding ammonia monooxygenase (amo) found in the ammonia-oxidizing beta-proteobacteria, few amo sequences are available representing the gamma-proteobacteria. We sequenced the complete amo operon (amoCAB) for Nitrosococcus oceani (ATCC 19707), a marine, autotrophic, ammon...
