Chains	Accession	Name	Description	Comments	Source
A	PF08302	Fungal tRNA ligase phosphodiesterase domain (tRNA_lig_CPD)	Fungal tRNA ligase phosphodiesterase domain	This domain is found in fungal tRNA ligases and has cyclic phosphodiesterase activity [1]. tRNA ligases are enzymes required for the splicing of precursor tRNA molecules containing introns.	Domain
A	PF08303	tRNA ligase kinase domain (tRNA_lig_kinase)	tRNA ligase kinase domain	This domain is found in fungal tRNA ligases and has kinase activity [1]. tRNA ligases are enzymes required for the splicing of precursor tRNA molecules containing introns. This family contains a P-loop motif.	Domain
