PrfC subfamily. (531 aa) |
| | metG | methionine-tRNA ligase; Is required not only for elongation of protein synthesis but also for the initiation of all mRNA translation through initiator tRNA(fMet) aminoacylation; Belongs to the class-I aminoacyl-tRNA synthetase family. (676 aa) |
| | pth | peptidyl-tRNA hydrolase; The natural substrate for this enzyme may be peptidyl-tRNAs which drop off the ribosome during protein synthesis. Belongs to the PTH family. (192 aa) |
