cca | ligT | b3056 | b0147 | Fused tRNA nucleotidyl transferase/2'3'-cyclic phosphodiesterase/2'nucleotidase and phosphatase; Catalyzes the addition and repair of the essential 3'- terminal CCA sequence in tRNAs without using a nucleic acid template. Adds these three nucleotides in the order of C, C, and A to the tRNA nucleotide-73, using CTP and ATP as substrates and producing inorganic pyrophosphate. Also shows highest phosphatase activity in the presence of Ni(2+) and hydrolyzes pyrophosphate, canonical 5'-nucleoside tri- and diphosphates, NADP, and 2'-AMP with the production of Pi. Displays a metal-independent [...] | 2'-5' RNA ligase; Hydrolyzes RNA 2',3'-cyclic phosphodiester to an RNA 2'- phosphomonoester. In vitro, can also ligate 5' and 3' half-tRNA molecules with 2',3'-cyclic phosphate and 5'-hydroxyl termini, respectively, to the product containing the 2'-5' phosphodiester linkage. This reaction does not require ATP and is reversible. Belongs to the 2H phosphoesterase superfamily. ThpR family. | 0.622 |
