Powering down the Pfam website
On October 5th, we began redirecting traffic from Pfam (pfam.xfam.org) to InterPro (www.ebi.ac.uk/interpro). The Pfam website will remain available at pfam-legacy.xfam.org until January 2023, when it will be decommissioned. You can read more about the sunset period in our blog post.

Clan: aG_PT (CL0686)


Alpha-glutamyl/putrescinyl thymine phosphorylase Add an annotation

This clan includes alpha-glutamyl/putrescinyl thymine phosphorylase related entries. According to sequence analysis several clades have been identified such as Clade-1, a prototypical aG/PT-pyrophoshorylase and Clade-2 pyrophoshorylases which are mainly found mainly in caudoviruses and prophages, where they are usually linked to a P-loop kinase. Several phages possess both a clade-1 aG/PT-pyrophoshorylase domain and a clade-2 protein [1].

This clan contains 3 families and the total number of domains in the clan is 438. The clan was built by S El-Gebali.
