Protein

Pyruvate formate-lyase-activating enzyme

Gene

act

Organism
Streptococcus mutans serotype c (strain ATCC 700610 / UA159)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

Activation of pyruvate formate-lyase under anaerobic conditions by generation of an organic free radical, using S-adenosylmethionine and reduced flavodoxin as cosubstrates to produce 5'-deoxy-adenosine.

Catalytic activityi

S-adenosyl-L-methionine + dihydroflavodoxin + [formate C-acetyltransferase]-glycine = 5'-deoxyadenosine + L-methionine + flavodoxin semiquinone + [formate C-acetyltransferase]-glycin-2-yl radical.

Cofactori

Binds 1 4Fe-4S cluster. The cluster is coordinated with 3 cysteines and an exchangeable S-adenosyl-L-methionine (By similarity).By similarity
