Similar to Escherichia coli, Escherichia coli O157:H7, and Shigella flexneri putative 6-pyruvoyl tetrahydrobiopterin synthase YgcM or b2765 or z4075 or ecs3620 or sf2781 SWALL:PTPS_ECOLI (SWALL:Q46903) (121 aa) fasta scores: E(): 8.1e-44, 86.66% id in 120 aa.

Putative membrane protein; Involved in the import of queuosine (Q) precursors, required for Q precursor salvage; Belongs to the vitamin uptake transporter (VUT/ECF) (TC 2.A.88) family. Q precursor transporter subfamily.

Conserved hypothetical protein; Catalyzes the complex heterocyclic radical-mediated conversion of 6-carboxy-5,6,7,8-tetrahydropterin (CPH4) to 7-carboxy-7- deazaguanine (CDG), a step common to the biosynthetic pathways of all 7-deazapurine-containing compounds.

Anaerobic ribonucleoside-triphosphate reductase activating protein; Activation of anaerobic ribonucleoside-triphosphate reductase under anaerobic conditions by generation of an organic free radical, using S-adenosylmethionine and reduced flavodoxin as cosubstrates to produce 5'-deoxy-adenosine.

Queuine tRNA-ribosyltransferase; Catalyzes the base-exchange of a guanine (G) residue with the queuine precursor 7-aminomethyl-7-deazaguanine (PreQ1) at position 34 (anticodon wobble position) in tRNAs with GU(N) anticodons (tRNA-Asp, -Asn, -His and -Tyr). Catalysis occurs through a double-displacement mechanism. The nucleophile active site attacks the C1' of nucleotide 34 to detach the guanine base from the RNA, forming a covalent enzyme-RNA intermediate. The proton acceptor active site deprotonates the incoming PreQ1, allowing a nucleophilic attack on the C1' of the ribose to form th [...]

Putative exported protein; Similar to Salmonella typhimurium, and Salmonella typhi putative DNA uptake protein and related dna-binding proteins ybav or stm0453 or sty0495 SWALL:Q8XGV0 (EMBL:AE008716) (124 aa) fasta scores: E(): 5.3e-15, 48.78% id in 123 aa, and to Escherichia coli, and Shigella flexneri hypothetical protein ybav precursor ybav or b0442 or sf0387 SWALL:AAN42043 (EMBL:AE000150) (123 aa) fasta scores: E(): 2.8e-13, 49.19% id in 124 aa.

Putative SecY-interacting protein; Interacts with the SecY protein in vivo. May bind preferentially to an uncomplexed state of SecY, thus functioning either as a chelating agent for excess SecY in the cell or as a regulatory factor that negatively controls the translocase function. Belongs to the Syd family.

GMP synthase [glutamine-hydrolyzing]; Catalyzes the synthesis of GMP from XMP.

S-adenosylmethionine:tRNA ribosyltransferase-isomerase; Transfers and isomerizes the ribose moiety from AdoMet to the 7-aminomethyl group of 7-deazaguanine (preQ1-tRNA) to give epoxyqueuosine (oQ-tRNA).
