Overview

Basic information about this protein and its source genome.

Accession: PA1881
Assembly: Pseudomonas aeruginosa PAO1, complete genome
Gene: PA1881
Status: annotated
Amino acids: 153
Structure source: AlphaFold

GO:0051537 Binding to a 2 iron, 2 sulfur (2Fe-2S) cluster; this cluster consists of two iron atoms, with two inorganic sulfur atoms found between the irons and acting as bridging ligands. GO:0046872 Binding to a metal ion. GO:0016491 Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced. GO:0051536 Binding to an iron-sulfur cluster, a combination of iron and sulfur atoms.
