 17-105 4.13e-37

queuosine biosynthesis protein QueD; Members of this protein family, closely related to eukaryotic 6-pyruvoyl tetrahydrobiopterin synthase enzymes, are the QueD protein of queuosine biosynthesis. Queuosine is a hypermodified base in the wobble position of tRNAs for Tyr, His, Asp, and Asn in many species. This modification, although widespread, appears not to be important for viability. The queuosine precursor made by this enzyme may be converted instead to archeaosine as in some Archaea. [Protein synthesis, tRNA and rRNA base modification]

 17-134 3.24e-20

6-pyruvoyl tetrahydropterin synthase (PTPS). Folate derivatives are essential cofactors in the biosynthesis of purines, pyrimidines, and amino acids, as well as formyl-tRNA. Mammalian cells are able to utilize pre-formed folates after uptake by a carrier-mediated active transport system. Most microbes and plants lack this system and must synthesize folates de novo from guanosine triphosphate. One enzyme from this pathway is PTPS which catalyzes the conversion of dihydroneopterin triphosphate to 6-pyruvoyl tetrahydropterin. The functional enzyme is a hexamer of identical subunits.

6-pyruvoyl tetrahydropterin synthase-related domain; Members of this family are small proteins, or small domains of larger proteins, that occur in certain Firmicutes in the same regions as members of families TIGR03110 and TIGR03111. Members of TIGR03110 resemble exosortase, a proposed protein sorting transpeptidase (see TIGR02602). TIGR03111 represents a small clade among the group 2 glycosyltransferases. Members of the current protein family resemble eukaryotic known and prokaryotic predicted 6-pyruvoyl tetrahydropterin synthases.
