Function

function

Flavin transferase that catalyzes the transfer of the FMN moiety of FAD and its covalent binding to the hydroxyl group of a threonine residue in a target flavoprotein (By similarity).
Is likely involved in the modification of RnfG and RnfD. Required for nitrogen fixation (PubMed:8264535).
