The protein

Catalyzed reaction/ biological activity

• ATP synthesis see a video

Protein family

• ATPase delta chain family (single member, according to UniProt)

Structure

• 5T4O (PDB) (ATPase from E. coli, 25% identity) PubMed
• P37811 (AlphaFold)

Modification

• phosphorylated on Arg-159 PubMed

Effectors of protein activity

• ATPase activity is inhibited upon binding of Mg-ADP to AtpD PubMed

Localization

• membrane (Heterogeneous) PubMed
• peripheral via the F0 complex
• http://subtiwiki.uni-goettingen.de/v3/gene/view/E956A30D97B2941108880F3AD48620C4DB6E0EBD

Expression and Regulation

Operons

• Genes: atpI-atpB-atpE-atpF-atpH-atpA-atpG-atpD-atpC

  Description: PubMed

  Regulation

  • Rel dependent downregulation (Class I) during stringent response PubMed
  • the mRNA is processed between atpI and atpB by RNase Y, this requires the RicA-RicF-RicT complex PubMed

  Regulatory mechanism

  • stringent response: negative regulation, in stringent response
