Protein

Histone acetyltransferase type B catalytic subunit

Gene

HAT1

Organism
Ustilago maydis (strain 521 / FGSC 9021) (Corn smut fungus)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Catalytic component of the histone acetylase B (HAT-B) complex. Acetylates 'Lys-12' of histone H4 which is required for telomeric silencing. Has intrinsic substrate specificity that modifies lysine in recognition sequence GXGKXG. Involved in DNA double-strand break repair.By similarity

Catalytic activityi

Acetyl-CoA + [protein]-L-lysine = CoA + [protein]-N6-acetyl-L-lysine.By similarity
