Abstract

The recent structure and associated biochemical studies of the metazoan-specific p300/CBP and fungal-specific Rtt109 histone acetyltransferases (HATs) have provided new insights into the ancestral relationship between HATs and their functions. These studies point to a common HAT ancester that has evolved around a common structural framework to form HATs with divergent catalytic and substrate-binding properties. These studies also point to the importance of regulatory loops within HATs and autoacetylation in HAT function. Implications for future studies are discussed.
