Function

function

Bifunctional enzyme that catalyzes the GTP-dependent successive addition of multiple gamma-linked L-glutamates to the L-lactyl phosphodiester of 7,8-didemethyl-8-hydroxy-5-deazariboflavin (F420-0) to form polyglutamated F420 derivatives, and the FMNH2-dependent reduction of dehydro-F420-0 to form F420-0.

Catalytic activity

Cofactor

Protein has several cofactor binding sites:
Mg2+ (UniProtKB | Rhea| CHEBI:18420 )

Mn2+ (UniProtKB | Rhea| CHEBI:29035 )

Note: Binds 2 divalent metal cations per subunit. The ions could be magnesium and/or manganese.
K+ (UniProtKB | Rhea| CHEBI:29103 )

Note: Monovalent cation. The ion could be potassium.

Pathway

Cofactor biosynthesis; coenzyme F420 biosynthesis.
