Arginosuccinate synthase; Derived by automated computational analysis using gene prediction method: Protein Homology.

Diphthine synthase; S-adenosyl-L-methionine-dependent methyltransferase that catalyzes the trimethylation of the amino group of the modified target histidine residue in translation elongation factor 2 (EF-2), to form an intermediate called diphthine. The three successive methylation reactions represent the second step of diphthamide biosynthesis.

Ribosomal subunit interface protein; Catalyzes the conversion of 3'-phosphate to a 2',3'-cyclic phosphodiester at the end of RNA. The mechanism of action of the enzyme occurs in 3 steps: (A) adenylation of the enzyme by ATP; (B) transfer of adenylate to an RNA-N3'P to produce RNA-N3'PP5'A; (C) and attack of the adjacent 2'-hydroxyl on the 3'-phosphorus in the diester linkage to produce the cyclic end product. The biological role of this enzyme is unknown but it is likely to function in some aspects of cellular RNA processing.

Similar to yeast Dim2p protein that is essential for 40S ribosomal subunit; structural studies show binding to 3' end of 16S rRNA in complex with archaeal IF2 alpha; Derived by automated computational analysis using gene prediction method: Protein Homology.

Developmentally regulated G-protein 1; Derived by automated computational analysis using gene prediction method: Protein Homology.

N2,N2-dimethylguanosine tRNA methyltransferase; Dimethylates a single guanine residue at position 26 of a number of tRNAs using S-adenosyl-L-methionine as donor of the methyl groups; Belongs to the class I-like SAM-binding methyltransferase superfamily. Trm1 family.

Peptide chain release factor 1; Directs the termination of nascent peptide synthesis (translation) in response to the termination codons UAA, UAG and UGA.

Diphthamide biosynthesis protein; Catalyzes the first step of diphthamide biosynthesis, i.e. the transfer of the 3-amino-3-carboxypropyl group from S-adenosyl-L- methionine (SAM) to the C2 position of the imidazole ring of the target histidine residue in translation elongation factor 2 (EF-2). Belongs to the DPH1/DPH2 family.

16S rRNA methyltransferase; Specifically dimethylates two adjacent adenosines in the loop of a conserved hairpin near the 3'-end of 16S rRNA in the 30S particle. May play a critical role in biogenesis of 30S subunits. Belongs to the class I-like SAM-binding methyltransferase superfamily. rRNA adenine N(6)-methyltransferase family. RsmA subfamily.
