How the CCA-Adding Enzyme Selects Adenine over Cytosine in Position 76 of tRNA
Template:ABSTRACT PUBMED 21071662
Function
[CCA_ARCFU] 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.[1]
About this Structure
3ov7 is a 4 chain structure with sequence from Archaeoglobus fulgidus. Full crystallographic information is available from OCA.
