This CD, composed mainly of bacterial single-domain proteins, includes the Thermus thermophilus (Tt) YbaK-like protein, a homolog of the trans-acting Escherichia coli YbaK Cys-tRNA(Pro) deacylase and the Agrobacterium tumefaciens ProX Ala-tRNA(Pro) deacylase and also the cis-acting prolyl-tRNA synthetase-editing domain (ProRS-INS). While ProX and ProRS-INS hydrolyze misacylated Ala-tRNA(Pro), the E. coli YbaK hydrolyzes misacylated Cys-tRNA(Pro). A few CD members are N-terminal, YbaK-ProX-like domains of an uncharacterized protein with a C-terminal, predicted Fe-S protein domain.

Aminoacyl-tRNA editing domain; This domain is found either on its own or in association with the tRNA synthetase class II core domain (pfam00587). It is involved in the tRNA editing of mis-charged tRNAs including Cys-tRNA(Pro), Cys-tRNA(Cys), Ala-tRNA(Pro). The structure of this domain shows a novel fold.

Cys-tRNA(Pro) deacylase; This model represents the YbaK family, bacterial proteins whose full length sequence is homologous to an insertion domain in proline--tRNA ligases. The domain deacylates mischarged tRNAs. The YbaK protein of Haemophilus influenzae (HI1434) likewise deacylates Ala-tRNA(Pro), but not the correctly charged Pro-tRNA(Pro). A crystallographic study of HI1434 suggests a nucleotide binding function. Previously, a member of this family was described as EbsC and was thought to be involved in cell wall metabolism.

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).

 37-150 5.10e-14

This CD includes cysteinyl-tRNA(Pro) deacylases from Haemophilus influenzae and Escherichia coli and other related bacterial proteins. These trans-acting, single-domain proteins are homologs of ProX and also the cis-acting prolyl-tRNA synthetase (ProRS) inserted (INS) editing domain. The bacterial amino acid trans-editing enzyme YbaK is a deacylase that hydrolyzes cysteinyl-tRNA(Pro)'s mischarged by prolyl-tRNA synthetase. YbaK also hydrolyzes glycyl-tRNA's, alanyl-tRNA's, seryl-tRNA's, and prolyl-tRNA's. YbaK is homologous to the INS domain of prolyl-tRNA synthetase (ProRS) as well as the trans-editing enzyme ProX of Aeropyrum pernix which hydrolyzes alanyl-tRNA's and glycyl-tRNA's.

 37-117 2.88e-08

INS is an amino acid-editing domain inserted (INS) into the bacterial class II prolyl-tRNA synthetase (ProRS) however, this CD is not exclusively bacterial. It is also found at the N-terminus of the eukaryotic/archaea-like ProRS's of yeasts and single-celled parasites. ProRS catalyzes the attachment of proline to tRNA(Pro); proline is first activated by ATP, and then transferred to the acceptor end of tRNA(Pro). ProRS can inadvertently process noncognate amino acids such as alanine and cysteine, and to avoid such errors, in post-transfer editing, the INS domain deacylates mischarged Ala-tRNA(Pro), thus ensuring the fidelity of translation. Misacylated Cys-tRNA(Pro) is not edited by ProRS. In addition to the INS editing domain, the prokaryote-like ProRS protein contains catalytic and anticodon-binding domains which form a dimeric interface.

 38-116 6.36e-08

YeaK is an uncharacterized Echerichia coli protein with a YbaK-like domain of unknown function. The YbaK-like domain family includes the INS amino acid-editing domain of the bacterial class II prolyl tRNA synthetase (ProRS), and it's trans-acting homologs, YbaK, and ProX. 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 a single-domain INS homolog such as YbaK, ProX, or PrdX which supplies the function of INS in trans.

This CD includes bacterial (Agrobacterium tumefaciens and Caulobacter crescentus ProX, and Clostridium sticklandii PrdX) and eukaryotic (Plasmodium falciparum N-terminal ProRS editing domain) sequences. The C. sticklandii PrdX protein, a homolog of the YbaK and ProX proteins, and the prolyl-tRNA synthetase-editing domain (ProRS-INS), specifically hydrolyzes Ala-tRNA(Pro). In this CD, many of the eukaryotic editing domains are N-terminal and cis-acting, expressed from a multidomain ProRS, however, similar to the bacterial PrdX, the mammalian, amphibian, and echinoderm PrdX-like proteins are trans-acting, single-domain proteins.
