Basic information about this protein and its source genome.

Accession: VK055_4852
Assembly: Klebsiella pneumoniae subsp. pneumoniae strain ATCC 43816 KPPR1, complete genome
Gene: menF AIK83379.1
Status: annotated
Amino acids: 439
Structure source: AlphaFold + ColabFold

5.4.4.2

GO:0009058 A cellular process consisting of the biochemical pathways by which a living organism synthesizes chemical substances. This typically represents the energy-requiring part of metabolism in which simpler substances are transformed into more complex ones. GO:0009234 The chemical reactions and pathways resulting in the formation of any of the menaquinones. Structurally, menaquinones consist of a methylated naphthoquinone ring structure and side chains composed of a variable number of unsaturated isoprenoid residues. Menaquinones that have vitamin K activity and are known as vitamin K2. GO:0008909 Catalysis of the reaction: chorismate = isochorismate. GO:0000287 Binding to a magnesium (Mg) ion.

Ligand evidence

Ligands grouped by evidence source. PDB ligands keep the source crystal visible, and loaded crystals can be opened directly in the structure viewer.

70 records

Highest-confidence structural evidence: ligands co-crystallized with this exact protein. If the source PDB is loaded in TPW, use Open crystal to inspect it in the structure viewer.

No PDB structure with a co-crystallized ligand found for this exact protein.

Structural evidence inferred from similar proteins. The source crystal indicates where the ligand was observed; the UniProt column identifies the homologous protein carrying that ligand.
