Overview

Basic information about this protein and its source genome.

Accession: KP13_01264
Assembly: Klebsiella pneumoniae subsp. pneumoniae Kp13, complete sequence
Gene: AHE46670.1 cybC
Status: annotated
Amino acids: 128
Structure source: AlphaFold + ColabFold

GO:0022900 A process in which a series of electron carriers operate together to transfer electrons from donors to any of several different terminal electron acceptors. GO:0042597 The region between the inner (cytoplasmic) and outer membrane (Gram-negative Bacteria) or cytoplasmic membrane and cell wall (Fungi and Gram-positive Bacteria). GO:0005506 Binding to an iron (Fe) ion. GO:0009055 A molecular function representing the directed movement of electrons from one molecular entity to another, typically mediated by electron carriers or acceptors, resulting in the transfer of energy and/or the reduction-oxidation (redox) transformation of chemical species. This activity is fundamental to various biological processes, including cellular respiration and photosynthesis, as well as numerous enzymatic reactions involved in metabolic pathways. GO:0020037 Binding to a heme, a compound composed of iron complexed in a porphyrin (tetrapyrrole) ring.
