General annotation (Comments)

Function

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 By similarity. HAMAP-Rule MF_01263 SAAS SAAS002646

Catalytic activity

A tRNA precursor + 2 CTP + ATP = a tRNA with a 3' CCA end + 3 diphosphate. HAMAP-Rule MF_01263 SAAS SAAS002646

Cofactor

Magnesium By similarity. HAMAP-Rule MF_01263 SAAS SAAS002646

Subunit structure

Homodimer By similarity. HAMAP-Rule MF_01263 SAAS SAAS002646

Miscellaneous

A single active site specifically recognizes both ATP and CTP and is responsible for their addition By similarity. HAMAP-Rule MF_01263

Sequence similarities

Belongs to the tRNA nucleotidyltransferase/poly(A) polymerase family. Bacterial CCA-adding enzyme type 3 subfamily. HAMAP-Rule MF_01263
