摘要：

Genes for respiratory nitrite reduction (denitrification) of Pseudomonas stutzeri are clustered within 7 kbp. A 4.6-kbp Hind III-Kpn I fragment carrying nirS, the structural gene for cytochrome cd1, was sequenced. An open reading frame immediately downstream of nirS codes for a 22.8-kDa protein with four heme c-binding motifs. Mutagenesis of this gene causes an apparent defect in electron donation to cytochrome cd1. Following this ORF are the structural genes for cytochrome c552, cytochrome c551, and ORF5 that codes for a 11.9-kDa monoheme protein. All cytochromes have a signal sequence for protein export.
