2.3.1.1 | hanging drop method |
704460, 704614 |
2.3.1.1 | in complex with with AcCoA and L-glutamate. The overall structure adopts a classic fold of the GCN5-related N-acetyltransferase family, characterized by a V-shaped cleft and beta-bulge. Activity depends on dimerization to form a deep, vast pocket for L-glutamate binding. L-glutamate binds at a site far away from AcCoA. A one-step sequential mechanism is proposed for enzymatic catalysis |
