This domain is found towards the N terminus of a group of animal of monooxygenases that play a crucial role in the regulation of the actin cytoskeleton. These enzymes promote the depolymerisation of F-actin by oxidising specific methionine residues on actin, leading to the formation of methionine -sulfoxide, which results in actin filament disassembly and prevents repolymerisation. This domain adopts a Rossman fold.	Domain
A	PF01494	FAD binding domain (FAD_binding_3)	FAD binding domain	This domain is involved in FAD binding in a number of enzymes.	Domain
