Summary: A circularly permuted ATPgrasp
The Pfam group coordinates the annotation of Pfam families in Wikipedia, but we have not yet assigned a Wikipedia article to this family. If you think that a particular Wikipedia article provides good annotation, please let us know.
A circularly permuted ATPgrasp Provide feedback
An ATP-grasp family that is present both as catalytically active and inactive versions. Contextual analysis suggests that it functions in a distinct peptide synthesis/modification system that additionally contains a transglutaminase, an NTN-hydrolase, the Alpha-E domain, and a transglutaminase fused N-terminal to a circularly permuted COOH-NH2 ligase. The inactive forms are often fused N-terminal to the Alpha-E domain .

The ATP-grasp domain is found in a wide variety of carboxylate-amine/thiol ligases . It is composed of two subdomains, with ATP being bound in the cleft between the two.
The clan contains the following 20 members:ATP-grasp ATP-grasp_2 ATP-grasp_3 ATP-grasp_4 ATP-grasp_5 ATPgrasp_ST ATPgrasp_Ter ATPgrasp_TupA ATPgrasp_YheCD CP_ATPgrasp_1 CP_ATPgrasp_2 CPSase_L_D2 Dala_Dala_lig_C DUF1297 GARS_A GSH-S_ATP Ins134_P3_kin RimK Synapsin_C TTL
We make a range of alignments for each Pfam-A family:
- the curated alignment from which the HMM for the family is built
- the alignment generated by searching the sequence database using the HMM
- Representative Proteomes (RPs) at 15%, 35%, 55% and 75% co-membership thresholds
- alignment generated by searching the NCBI sequence database using the family HMM
- alignment generated by searching the metagenomics sequence database using the family HMM
You can see the alignments as HTML or in three different sequence viewers:
- Pfam viewer
- an HTML-based viewer that uses DAS to retrieve alignment fragments on request

For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the PDBe group, to allow us to map Pfam domains onto UniProt sequences and three-dimensional protein structures. The table below shows the structures on which the CP_ATPgrasp_1 domain has been found. There are 1 instances of this domain found in the PDB. Note that there may be multiple copies of the domain in a single PDB structure, since many structures contain multiple copies of the same protein seqence.
