Overview

Basic information about this protein and its source genome.

Accession: KP13_04210
Assembly: Klebsiella pneumoniae subsp. pneumoniae Kp13, complete sequence
Gene: dmsA AHE45441.1
Status: annotated
Amino acids: 812
Structure source: AlphaFold + ColabFold

GO:0051539 Binding to a 4 iron, 4 sulfur (4Fe-4S) cluster; this cluster consists of four iron atoms, with the inorganic sulfur atoms found between the irons and acting as bridging ligands. GO:0009389 Catalysis of the reaction: dimethyl sulfide + a menaquinone + H2O = dimethyl sulfoxide + a menaquinol. 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:0030151 Binding to a molybdenum ion (Mo). GO:0043546 Binding to a molybdopterin cofactor (Moco), essential for the catalytic activity of some enzymes, e.g. sulfite oxidase, xanthine dehydrogenase, and aldehyde oxidase. The cofactor consists of a mononuclear molybdenum (Mo-molybdopterin) or tungsten ion (W-molybdopterin) coordinated by one or two molybdopterin ligands. GO:0030288 The region between the inner (cytoplasmic or plasma) membrane and outer membrane of organisms with two membranes such as Gram negative bacteria. These periplasmic spaces are relatively thick and contain a thin peptidoglycan layer (PGL), also referred to as a thin cell wall.
