-
short-chain RNA molecules present in the cell (in at least 20 varieties, each variety capable of combining with a specific amino acid) that attach the correct amino acid to the protein chain that is being synthesized at the ribosome of the cell (according to directions coded in the mRNA)

-
The small RNA molecules, 73-80 nucleotides long, that function during translation (TRANSLATION, GENETIC) to align AMINO ACIDS at the RIBOSOMES in a sequence determined by the mRNA (RNA, MESSENGER). There are about 30 different transfer RNAs. Each recognizes a specific CODON set on the mRNA through its own ANTICODON and as aminoacyl tRNAs (RNA, TRANSFER, AMINO ACYL), each carries a specific amino acid to the ribosome to add to the elongating peptide chains.

Procollagen Proline Dioxygenase
- mixed-function oxygenase that catalyzes hydroxylation prolyl-glycyl-containing-peptide, usually in protocollagen, hydroxyprolylglycyl-peptide. The enzyme utilizes molecular oxygen with a concomitant oxidative decarboxylation of 2-oxoglutarate to succinate. EC 1.14.11.2.
