Overview

Basic information about this protein and its source genome.

Accession: VK055_2986
Assembly: Klebsiella pneumoniae subsp. pneumoniae strain ATCC 43816 KPPR1, complete genome
Gene: AIK81571.1
Status: annotated
Amino acids: 559
Structure source: AlphaFold + ColabFold

GO:0015942 The chemical reactions and pathways involving formate, also known as methanoate, the anion HCOO- derived from methanoic (formic) acid. 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:0008863 Catalysis of the reaction: formate + NAD+ = CO2 + NADH. 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:0016020 A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it. GO:1990204 Any protein complex that possesses oxidoreductase activity.

PDB and ChEMBL records on this protein are shown in full. ChEMBL records from similar proteins are capped at the top 100 per protein (by pchembl) and ZINC at the top 50 (Tanimoto ≥ 0.5). ADME columns are descriptor-based screening flags, not experimental toxicity results.
