== Function ==
[https://www.uniprot.org/uniprot/SOXA_ANCN5 SOXA_ANCN5] C-type monoheme cytochrome, which is part of the SoxAX cytochrome complex involved in sulfur oxidation. The SoxAX complex catalyzes the formation of a heterodisulfide bond between the conserved cysteine residue on a sulfur carrier SoxYZ complex subunit SoxY and thiosulfate or other inorganic sulfur substrates. This leads to the liberation of two electrons, which may be transferred from the SoxAX complex to another cytochrome c that then channels them into the respiratory electron transport chain. Some electrons may be used for reductive CO(2) fixation.<ref>PMID:14645228</ref> <ref>PMID:15848194</ref> <ref>PMID:18552405</ref> <ref>PMID:21592966</ref>
