Identification
Name: Ferricytochrome c
Description:Cytochrome c, or Cyt c, is a small heme protein and a component of the oxidative phosphorylation electron transport chain. The heme group of cytochrome c accepts electrons from the Cytochrome b-c1 complex (Complex III) and transfers electrons to the Cytochrome oxidase complex (Complex IV). Cyt c is capable of undergoing oxidation and reduction, but does not bind oxygen. Cytochrome c is a highly conserved protein across the spectrum of species, found in plants, animals, and many unicellular organisms. This, along with its small size (molecular weight about 12,000 daltons), makes it useful in studies of cladistics. Its primary structure consists of a chain of about 100 amino acids. (Wikipedia)

General function:
Involved in oxidoreductase activity
Specific function:
Catalytic subunit of the periplasmic nitrate reductase (NAP). Only expressed at high levels during aerobic growth.

Protein Details
• Nitrate reductase molybdenum cofactor assembly chaperone NarJ
General function:
Involved in unfolded protein binding
Specific function:
Chaperone required for proper molybdenum cofactor insertion and final assembly of the membrane-bound respiratory nitrate reductase 1. Required for the insertion of the molybdenum into the apo-NarG subunit, maybe by keeping NarG in an appropriate competent-open conformation for the molybdenum cofactor insertion to occur. NarJ maintains the apoNarGH complex in a soluble state. Upon insertion of the molybdenum cofactor, NarJ seems to dissociate from the activated soluble NarGH complex, before its association with the NarI subunit on the membrane
Gene Name:
narJ
Locus Tag:
PA3873
Molecular weight:
27.3 kDa
