Pcal_0569

Gene
Pcal_0569
Protein
Protein archease
Organism
Pyrobaculum calidifontis (strain JCM 11548 / VA1)
Length
147 amino acids
Function
Activates the tRNA-splicing ligase complex by facilitating the enzymatic turnover of catalytic subunit RtcB. Acts by promoting the guanylylation of RtcB, a key intermediate step in tRNA ligation. Can also alter the NTP specificity of RtcB such that ATP, dGTP or ITP is used efficiently (By similarity).
Similarity
Belongs to the archease family.
