The Gcn5-Ada2-Ada3 (ADA) histone acetyltransferase complexes have the capacity to crotonylate histones and crotonylate lysines in the N-terminal tails of histone H3 and H4. Crotonylation selectively affects gene transcription in vivo in a manner dependent on Gcn5 and Esa1.
Title: Gcn5 and Esa1 function as histone crotonyltransferases to regulate crotonylation-dependent transcription.
work argues that nonhistone protein acetylation by Gcn5 is determined in part by specific amino acids surrounding target lysines but that even optimal sequences require both Ada2 and Ada3 for robust acetylation.
Title: A synthetic non-histone substrate to study substrate targeting by the Gcn5 HAT and sirtuin HDACs.
the Ada2 SANT domain does not activate Gcn5's activity by directly affecting histone peptide binding as previously proposed. Instead, the Ada2 SANT domain enhances Gcn5 binding of the enzymatic cosubstrate acetyl-CoA.
Title: Structural basis for activation of SAGA histone acetyltransferase Gcn5 by partner subunit Ada2.
This replication-guided H3K9ac was fully dependent on the acetyltransferase Rtt109, while expression-guided H3K9ac was deposited by Gcn5. Further, topoisomerase depletion intensified H3K9ac in front of the replication fork and in sites where RNA polymerase II was trapped, suggesting supercoiling stresses trigger H3K9 acetylation.
Title: Chromatin dynamics during DNA replication.
It conserved Spt-Ada-Gcn5 acetyltransferase (SAGA) complex as a paradigm to illustrate how co-activators share and combine a relatively limited set of functional tools.
Title: Sharing the SAGA.
Gcn5 acetyltransferase synergizes with Spt3 (TBP-binding) to promote transcription.

NP_011768.1

EC 2.3.1.48

Catalytic subunit of ADA and SAGA histone acetyltransferase complexes; modifies N-terminal lysines on histones H2B and H3; acetylates Rsc4p, a subunit of the RSC chromatin-remodeling complex, altering replication stress tolerance; relocalizes to the cytosol in response to hypoxia; mutant displays reduced transcription elongation in the G-less-based run-on (GLRO) assay; greater involvement in repression of RNAPII-dependent transcription than in activation
