This family of proteins is found in certain bacterial lineages. In staphylococcus this protein is known to be Glycosyl-4,4'-diaponeurosporenoate acyltransferase an enzyme involved in the final step of synthesis of staphyloxanthin, an orange pigment found in most S. aureus strains. Proteins in this family are typically between 157 and 184 amino acids in length. Members of the family contain and EXXH motif that may be functionally important.
