Heterodisulfide reductase, subunit C (hdrC); Part of a complex that catalyzes the reversible reduction of CoM-S-S-CoB to the thiol-coenzymes H-S-CoM (coenzyme M) and H-S-CoB (coenzyme B); Belongs to the HdrC 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.

Proteasome, subunit alpha (psmA); Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation. The M.jannaschii proteasome is able to cleave oligopeptides after Glu, Asp, Tyr, Phe, Trp, slightly after Arg, but not after Ala. Thus, displays caspase-like and chymotrypsin-like activities and low level of trypsin- like activity.

Conserved hypothetical protein; Similar to GB:AE000782 percent identity: 34.62; identified by sequence similarity; putative.

Conserved hypothetical protein; RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication.

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; Similar to GB:AE000782 percent identity: 52.42; identified by sequence similarity; putative.

erpK protein isolog; Molecular chaperone capable of stabilizing a range of proteins. Seems to fulfill an ATP-independent, HSP70-like function in archaeal de novo protein folding (By similarity).
