6.1.1.11 | Pex21p |
the enzyme interacts with the peroxisome biogenesis-related factor Pex21p, the C-terminally appended domain of yeast seryl-tRNA synthetase does not participate in substrate binding, but instead is required for association with Pex21p, Pex21p does not directly bind tRNA, and nor does it possess a tRNA-binding motif, but it instead participates in the formation of a specific ternary complex with seryl-tRNA synthetase and tRNASer, strengthening the interaction of seryl-tRNA synthetase with its cognate tRNASer, overview |
