prolyl-tRNA synthetase, family I; Prolyl-tRNA synthetase is a class II tRNA synthetase and is recognized by pfam model tRNA-synt_2b, which recognizes tRNA synthetases for Gly, His, Ser, and Pro. The prolyl-tRNA synthetases are divided into two widely divergent families. This family includes the archaeal enzyme, the Pro-specific domain of a human multifunctional tRNA ligase, and the enzyme from the spirochete Borrelia burgdorferi. The other family includes enzymes from Escherichia coli, Bacillus subtilis, Synechocystis PCC6803, and one of the two prolyL-tRNA synthetases of Saccharomyces cerevisiae.

YbaK-like. The YbaK family of deacylase domains includes the INS amino acid-editing domain of the bacterial class II prolyl tRNA synthetase (ProRS), and it's trans-acting homologs, YbaK, ProX, and PrdX. The primary function of INS is to hydrolyze mischarged cysteinyl-tRNA(Pro)'s, thus helping ensure the fidelity of translation. Organisms whose ProRS lacks the INS domain express an INS homolog in trans (e.g. YbaK, ProX, or PrdX).

Class II tRNA amino-acyl synthetase-like catalytic core domain. Class II amino acyl-tRNA synthetases (aaRS) share a common fold and generally attach an amino acid to the 3' OH of ribose of the appropriate tRNA. PheRS is an exception in that it attaches the amino acid at the 2'-OH group, like class I aaRSs. These enzymes are usually homodimers. This domain is primarily responsible for ATP-dependent formation of the enzyme bound aminoacyl-adenylate. The substrate specificity of this reaction is further determined by additional domains. Intererestingly, this domain is also found is asparagine synthase A (AsnA), in the accessory subunit of mitochondrial polymerase gamma and in the bacterial ATP phosphoribosyltransferase regulatory subunit HisZ.
