Conserved hypothetical protein; Similar to GP:1001812 percent identity: 32.62; identified by sequence similarity; putative; Belongs to the archaeal NMN adenylyltransferase family.

Queuine tRNA-ribosyltransferase (tgtA); Exchanges the guanine residue with 7-cyano-7-deazaguanine (preQ0) at position 15 in the dihydrouridine loop (D-loop) of archaeal tRNAs. Can also utilize guanine as substrate.

Conserved hypothetical protein; Similar to GB:AE000666 percent identity: 42.44; identified by sequence similarity; putative; Belongs to the metallo-dependent hydrolases superfamily.

Putative transcription initiation factor (TFIIE, subunit alpha); Transcription factor that plays a role in the activation of archaeal genes transcribed by RNA polymerase. Facilitates transcription initiation by enhancing TATA-box recognition by TATA-box-binding protein (Tbp), and transcription factor B (Tfb) and RNA polymerase recruitment. Not absolutely required for transcription in vitro, but particularly important in cases where Tbp or Tfb function is not optimal. It dynamically alters the nucleic acid-binding properties of RNA polymerases by stabilizing the initiation complex and d [...]

Conserved hypothetical protein; Contacts the emerging nascent chain on the ribosome. Belongs to the NAC-alpha family.

NADH oxidase; Similar to GB:AE000782 percent identity: 43.64; identified by sequence similarity; putative.

Conserved hypothetical protein; Similar to PID:1651806 percent identity: 33.88; identified by sequence similarity; putative; Belongs to the LarC family.

Putative transmembrane oligosaccharyl transferase; Oligosaccharyl transferase (OST) that catalyzes the initial transfer of a defined glycan (ManNAcGlc-2,3-diNAcAGlcNAc in Methanococci) from the lipid carrier dolichol-monophosphate to an asparagine residue within an Asn-X-Ser/Thr consensus motif in nascent polypeptide chains, the first step in protein N-glycosylation. Involved in the assembly of an N-linked disaccharide that decorates the S-layer glycoprotein and flagellins.
