This short domain is found in Heterotetrameric Sarcosine Oxidase's alpha A3 domain [1]. This domain binds to FMN in sarcosine oxidase. This domain is related to Pfam:PF04324 but lacks its iron binding cysteine residues.
This family includes both class I and class II oxidoreductases and also NADH oxidases and peroxidases. This domain is actually a small NADH binding domain within a larger FAD binding domain.
The 2Fe-2S ferredoxin family have a general core structure consisting of beta(2)-alpha-beta(2) which a beta-grasp type fold. The domain is around one hundred amino acids with four conserved cysteine residues to which the 2Fe-2S cluster is ligated. Th ...
The 2Fe-2S ferredoxin family have a general core structure consisting of beta(2)-alpha-beta(2) which a beta-grasp type fold. The domain is around one hundred amino acids with four conserved cysteine residues to which the 2Fe-2S cluster is ligated. This cluster appears within sarcosine oxidase proteins.
