 26-149 1.46e-29

tRNA N6-adenosine threonylcarbamoyltransferase; This domain can be found in Kae1/Qri7/YgjD, products of COG0533 that belong to a small group of 60 proteins that are present in all three domains of life. COG0533 proteins are suggest to play a role in a post translational modification of certain tRNAs. For example, YgjD along with YeaZ, YjeE, and YrdC have been deemed necessary and sufficient for the tRNA modification. This modification involves the formation of N6-threonyl carbamoyl adenosine (t6A) at position 37 in the anti-codon stem loop which is critical for translational speed and accuracy. Structural analysis indicate that YeaZ lacks resemblance to any known protease active site. Together with the absence of a putative zinc-binding motif. Thus the likelyhood of it being a protease, as previously thought, has been negated. EC:2.3.1.234

 3-199 7.39e-49

nucleotide-binding domain (NBD) of the Kae1/TsaB-like domain family; The family includes tRNA N6-adenosine threonylcarbamoyltransferase Kae1/TsaD, tRNA threonylcarbamoyladenosine biosynthesis protein TsaB (previously known as YeaZ), as well as proteins from the NodU/CmcH subfamily. tRNA N6-adenosine threonylcarbamoyltransferase (EC 2.3.1.234) is required for the formation of a threonylcarbamoyl group on adenosine at position 37 (t(6)A37) in tRNAs that read codons beginning with adenine. It is involved in the transfer of the threonylcarbamoyl moiety of threonylcarbamoyl-AMP (TC-AMP) to the N6 group of A37. TsaB is required for the formation of a threonylcarbamoyl group on adenosine at position 37 (t(6)A37) in tRNAs that read codons beginning with adenine. It may be involved in the transfer of the threonylcarbamoyl moiety of threonylcarbamoyl-AMP (TC-AMP) to the N6 group of A37, together with TsaD and TsaE. TsaB seems to play an indirect role in the t(6)A biosynthesis pathway, possibly in regulating the core enzymatic function of TsaD. The NodU/CmcH family includes NodU from Rhizobium, CmcH from Amycolatopsis lactamdurans, the bifunctional carbamoyltransferase TobZ from Streptoalloteichus tenebrarius, NovN from Streptomyces niveus and NolNO from Sinorhizobium fredii. NodU is a Rhizobium nodulation protein involved in the synthesis of nodulation factors has 6-O-carbamoyltransferase-like activity. 3'-hydroxymethylcephem-O-carbamoyltransferase CmcH (EC 2.1.3.7) is involved in cephamycin (antibiotic) biosynthesis and has 3-hydroxymethylcephem carbamoyltransferase activity. nebramycin 5' synthase TobZ (EC 6.1.2.2) functions as an ATP carbamoyltransferase and tobramycin carbamoyltransferase. Novobiocin biosynthesis protein NovN (EC 2.1.3.12) acts as a carbamoyltransferase that mediates 3'-carbamoylation of the noviosyl ring to produce novobiocin, the final step in the novobiocin biosynthesis pathway. nodulation protein NolNO (EC 2.1.3.-) is involved in the O-carbamoylation of nod factors. The NodU/CmcH subfamily proteins consist of two domains. Only the N-terminal domain shows similarity with Kae1/TsaB-like domain, which belongs to the ASKHA (Acetate and Sugar Kinases/Hsc70/Actin) superfamily of phosphotransferases, all members of which share a common characteristic five-stranded beta sheet occurring in both the N- and C-terminal domains.

 26-149 1.46e-29

tRNA N6-adenosine threonylcarbamoyltransferase; This domain can be found in Kae1/Qri7/YgjD, products of COG0533 that belong to a small group of 60 proteins that are present in all three domains of life. COG0533 proteins are suggest to play a role in a post translational modification of certain tRNAs. For example, YgjD along with YeaZ, YjeE, and YrdC have been deemed necessary and sufficient for the tRNA modification. This modification involves the formation of N6-threonyl carbamoyl adenosine (t6A) at position 37 in the anti-codon stem loop which is critical for translational speed and accuracy. Structural analysis indicate that YeaZ lacks resemblance to any known protease active site. Together with the absence of a putative zinc-binding motif. Thus the likelyhood of it being a protease, as previously thought, has been negated. EC:2.3.1.234

nucleotide-binding domain (NBD) of O-sialoglycoprotein endopeptidase-like protein 1 (OSGEPL1) and similar proteins from eukayotes; The family includes mammalian OSGEPL1 and yeast QRI7, which are the mitochondrial orthologs of the universal Kae1/ TsaD (also known as YgjD) protein. OSGEPL1/QRI7 (EC 2.3.1.234), also called mitochondrial tRNA N6-adenosine threonylcarbamoyltransferase, N6-L-threonylcarbamoyladenine synthase, t(6)A synthase, t(6)A37 threonylcarbamoyladenosine biosynthesis protein, or tRNA threonylcarbamoyladenosine biosynthesis protein, is required for the formation of a threonylcarbamoyl group on adenosine at position 37 (t(6)A37) in mitochondrial tRNAs that read codons beginning with adenine. It is probably involved in the transfer of the threonylcarbamoyl moiety of threonylcarbamoyl-AMP (TC-AMP) to the N6 group of A37. It is involved in mitochondrial genome maintenance.
