Namequinoprotein cytochrome relay system
DescriptionThis system features a putative carrier protein, TIGR04557, related to the SoxY and SoxZ carrier complex of the sulfate oxidation cycle, as well as PQQ-dependent enzymes that have a Cys-Cys motif, and specialized cytochromes involved in electron transport. Authentic SoxY (see TIGR04488) is a carrier protein for sulfur oxidation, with a covalent attachment site near its C-terminus, a Cys residue in the context GGCGG or GGCG. The carrier Cys of SoxY is conserved in TIGR04557, but what might be attached in the latter is unknown. Note that GenProp0895 (alcohol ABC transporter, PedABC-type) describes a four-gene operon closely tied to this system.
