The complex is probably involved in the transfer of the threonylcarbamoyl moiety of threonylcarbamoyl-AMP (TC-AMP) to the N6 group of A37. OSGEP likely plays a direct catalytic role in this reaction but requires other protein(s) of the complex to fulfill this activity. OSGEP is the mammalian orthologue of kinase-associated endopeptidase Kae1.

The pair, which appears universal in the archaea, corresponds to EKC/KEOPS complex in eukaryotes. A recent characterization of the member from Pyrococcus abyssi, as an iron-binding, atypical DNA-binding protein with an apurinic lyase activity, challenges the common annotation of close homologs as O-sialoglycoprotein endopeptidase. The latter annotation is based on a characterized protein from the bacterium Pasteurella haemolytica. [DNA metabolism, DNA replication, recombination, and repair]

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

metallohydrolase, glycoprotease/Kae1 family; This subfamily includes the well-studied secreted O-sialoglycoprotein endopeptidase (glycoprotease, EC 3.4.24.57) of Pasteurella haemolytica, a pathogen. A member from Riemerella anatipestifer, associated with cohemolysin activity, likewise is exported without benefit of a classical signal peptide and shows glycoprotease activity on the test substrate glycophorin. However, archaeal members of this subfamily show unrelated activities as demonstrated in Pyrococcus abyssi: DNA binding, iron binding, apurinic endonuclease activity, genomic association with a kinase domain, and no glycoprotease activity. This family thus pulls together a set of proteins as a homology group that appears to be near-universal in life, yet heterogeneous in assayed function between bacteria and archaea.

tRNA threonylcarbamoyl adenosine modification protein TsaD; This model represents bacterial members of a protein family that is widely distributed. In a few pathogenic species, the protein is exported in a way that may represent an exceptional secondary function. This model plus companion (archaeal) model TIGR03722 together span the prokaryotic member sequences of TIGR00329, a protein family that appears universal in life, and whose broad function is unknown. A member of TIGR03722 has been characterized as a DNA-binding protein with apurinic endopeptidase activity. In contrast, the rare characterized members of the present family show O-sialoglycoprotein endopeptidase (EC. 3.4.24.57) activity after export. These include glycoprotease (gcp) from Pasteurella haemolytica A1 and a cohemolysin from Riemerella anatipestifer (GB|AAG39646.1). The member from Staphylococcus aureus is essential and is related to cell wall dynamics and the modulation of autolysis, but members are also found in the Mycoplasmas (which lack a cell wall). A reasonable hypothesis is that virulence-related activities after export are secondary to a bacterial domain-wide unknown function. [Protein synthesis, tRNA and rRNA base modification]

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.
