Cloning, heterologous expression, and characterization of recombinant class II cytochromes c from Rhodopseudomonas palustris.

Abstract

The cytochrome (cyt) c', cyt c(556), and cyt c(2) genes from Rhodopseudomonas palustris have been cloned; recombinant cyt c' and cyt c(556) have been expressed, purified, and characterized. Unlike mitochondrial cyt c, these two proteins are structurally similar to cyt b(562), in which the heme is embedded in a four-helix bundle. The hemes in both… (More)
