FAD-binding, type 2, subdomain 1 <p>These FAD-binding domains consist of two alpha+beta subdomains. This entry represents the first (N-terminal) 2-layer alpha/beta subdomain, which is found in:</p><p> <ul><li>FAD-linked oxidases (N-terminal domain), such as vanillyl-alochol oxidase (<db_xref db="EC" dbkey="1.1.3.38"/>) [<cite idref="PUB00030304"/>], flavoprotein subunit of p-cresol methylhydroxylase (<db_xref db="EC" dbkey="1.17.99.1"/>) [<cite idref="PUB00032326"/>], D-lactate dehydrogenases (<db_xref db="EC" dbkey="1.1.1.28"/>, <db_xref db="EC" dbkey="1.1.2.4"/> -cytochrome) [<cite idref="PUB00024738"/>], Cholesterol oxidases (<db_xref db="EC" dbkey="1.1.3.6"/>) [<cite idref="PUB00025871"/>], Cytokinin dehydrogenase 1 (<db_xref db="EC" dbkey="1.5.99.12"/>) [<cite idref="PUB00032155"/>].</li><li>Uridine diphospho-N-acetylenolpyruvylglucosamine reductase (MurB) (N-terminal domain) [<cite idref="PUB00031941"/>].</li><li>CO dehydrogenase flavoprotein (N-terminal domain; [<cite idref="PUB00036706"/>]) family, which includes xanthine oxidase (domain 3) (<db_xref db="EC" dbkey="1.17.3.2"/>) [<cite idref="PUB00032033"/>], subunit A of xanthine dehydrogenase (domain 3) (<db_xref db="EC" dbkey="1.17.1.4"/>) [<cite idref="PUB00026513"/>], medium subunit of quinoline 2-oxidoreductase (QorM) (<db_xref db="EC" dbkey="1.3.99.17"/>) [<cite idref="PUB00031318"/>], and the beta-subunit of 4-hydroxybenzoyl-CoA reductase (HrcB) (N-terminal domain) (<db_xref db="EC" dbkey="1.3.99.20"/>) [<cite idref="PUB00030724"/>].</li></ul> </p>
