Descriptions
Acetyltransferase Pat is a single Gcn5-like enzyme, in which Gcn5-like PAT domain enables direct cAMP control of protein acetylation. The crystal structures of the autoinhibited and cAMP-activated Pat reveal that cAMP binds to a cryptic site in the regulatory domain. An extensive conformational rearrangement relieves the autoinhibition by means of a substrate-mimicking lid that covers the protein-substrate binding surface.

5 GO annotations of molecular function
| Name | Definition |
|---|---|
| acetyltransferase activity | Catalysis of the transfer of an acetyl group to an acceptor molecule. |
| acyltransferase activity | Catalysis of the transfer of an acyl group from one compound (donor) to another (acceptor). |
| cAMP binding | Binding to cAMP, the nucleotide cyclic AMP (adenosine 3',5'-cyclophosphate). |
| DNA-binding transcription factor activity | A transcription regulator activity that modulates transcription of gene sets via selective and non-covalent binding to a specific double-stranded genomic DNA sequence (sometimes referred to as a motif) within a cis-regulatory region. Regulatory regions include promoters (proximal and distal) and enhancers. Genes are transcriptional units, and include bacterial operons. |
| metal ion binding | Binding to a metal ion. |
