Domain

ATP-grasp domain, R2K clade family 3 (IPR025643)

Short name: R2K_3

Overlapping homologous superfamilies

None.

Domain relationships

None.

Description

Proteins containing this domain are a group of ATP-grasp enzymes belonging to the R2K clade, wherein one of the absolutely-conserved lysine residues has migrated to the RAGYNA domain which is a part of the core ATP-grasp module. This family is predicted to catalyze peptide ligation reactions on protein substrates in biological conflict contexts, probably between bacteriophages and their hosts [PMID: 25976611].
