Note: the initiator tRNA is the only member of the tRNA family that can bind directly to the P site.
Initiation factors
Proteins that promote the binding of ribosomes and the initiator tRNA to mRNA to begin the process of translation.
Inoculum
The initial sample of a microorganism added to a medium used to start a new culture.
Initiation factor One of a set of proteins that assist in the association of the ribosome, mrna, and initiator trna to initiate the process of protein synthesis.
In eukaryotes and archaea, the amino acid encoded by the start codon is methionine. The initiator tRNA charged with Met forms part of the ribosomal complex and thus all proteins start with this amino acid (unless it is cleaved away by a protease in ...
