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. tRNA 3'-terminal CCA addition is required both for tRNA processing and repair. Also involved in tRNA surveillance by mediating tandem CCA addition to generate a CCACCA at the 3' terminus of unstable tRNAs. While stable tRNAs receive only 3'-terminal CCA, unstable tRNAs are marked with CCACCA and rapidly degraded"],"length":397,"sequence":"MERFKKASSIIETLKQQGHEAYFVGGSVRDLIIDRPIGDIDIATSALPEEVMAIFPRHVPVGLEHGTVIVVENGEPYEVTTFRTESEYEDFRRPSSVQFVRSLEEDLKRRDFTMNAIAMTEEGKMVDLFAGQEAIQKREIMTVGNAADRFQEDALRMMRGIRFVSTLGFSLETKTKQAIETYGHLLEHIAIERITVEFEKLLTGTYCVKALKELVETKLFSHLPYLQMSEEKLLKATQYKWDSFEADIEAWAFFLYCIGEEHPAVFLRQWKFSNKKIKDIVAVLLTIRKRKEKDWDTVLLYKTGIHIAEMAERVYEAMIESYDHTAVNRVQTLFQALPIKNRQEMNVTGNDLLNWASKKPGPWVAEMIQKIEEAIVQGNVVNEKECIREWLQECNLL","proteome":null,"gene":"cca","go_terms":[{"identifier":"GO:0003723","name":"RNA binding","category":{"code":"F","name":"molecular_function"}},{"identifier":"GO:0016779","name":"nucleotidyltransferase activity","category":{"code":"F","name":"molecular_function"}},{"identifier":"GO:0006396","name":"RNA processing","category":{"code":"P","name":"biological_process"}},{"identifier":"GO:0004810","name":"CCA tRNA nucleotidyltransferase activity","category":{"code":"F","name":"molecular_function"}},{"identifier":"GO:0001680","name":"tRNA 3'-terminal CCA addition","category":{"code":"P","name":"biological_process"}}],"protein_evidence":3,"source_database":"reviewed","is_fragment":false,"in_alphafold":true,"in_bfvd":false,"ida_accession":"32cfc1308e1885dbe81b8f4fcc905da285e7a72e","counters":{"domain_architectures":5423,"entries":19,"isoforms":0,"proteomes":0,"sets":3,"structures":0,"taxa":1,"dbEntries":{"cathgene3d":4,"cdd":1,"ssf":2,"pfam":3,"hamap":1,"ncbifam":1,"panther":1,"interpro":6},"proteome":0,"taxonomy":1,"similar_proteins":5423}}}
