Nucleophilic acyl substit1
To totally bypass the involvement of an enzyme for expressed protein ligation, here we showed that a cysteine in a recombinant protein was chemically activated by a small molecule cyanylating reagent at its N-side amide for undergoing nucleophilic acyl substitution with amines including a number of l- and d-amino acids and hydrazine.

those in the large subunit are prefixed L. Ribosomal proteins have various roles, such as stabilizing rRNA, accelerating peptide bond formation (L27 and L16), and participating in extra-ribosomal functions (for example, S6 undergoes phosphorylation which helps to determine cell size and glucose homeostasis).
