PROSITE documentation PDOC51161 [for PROSITE entry PS51161]

ATP-cone domain profile





Description

The ATP-cone domain is an ATP-binding module of ~85-90 residues, which is found in association with other domains such as class I+II and class III ribonucleotide reductases (see <PDOC00084>), the P-loop kinase or a zinc ribbon. It can be found as a single copy or in two-three tandem copies [1].

The ATP-cone is a compact, globular N-terminal domain which includes four α-helices and three β-strands (see <PDB:3R1R>). The structure of the ATP-cone domain resembles a cone with the surface formed by the four helices and the top by a three-stranded β-sheet. ATP is bound at the top of the cone just below the β-sheet [1].

Some proteins known to contain an ATP-cone domain are listed below:

  • Ribonucleotide reductases (RNRs).
  • Archaeal and deinococcal 2-phophoglycerate kinases (2-PGKs).
  • Bacterial ybaD-like proteins.

The profile we developed covers the entire ATP-cone domain.
