AB  - Phage as an anti-bacterial agent must be efficient in killing bacteria, and consequently needs to replicate efficiently. Protein production is a limiting step in replication in almost all forms of life, including phages. Efficient protein production depends on the efficiency of translation initiation, elongation and termination, with translation initiation often being rate limiting. Initiation signals such as Shine-Dalgarno (SD) sequences and start codon are decoded by anti-SD sequences and initiation tRNA, respectively. While the decoding machinery cannot be readily modified, the signals can be engineered to increase the efficiency of their decoding. Here I review our understanding of the translation machinery to facilitate the engineering of optimal translation initiation signals for facilitating the design of phage protein-coding genes, including 1) accurate characterization of the 3’ end of 16S rRNA by using RNA-Seq data, 2) identification of the optimal SD/aSD interaction, and 3) reduction of secondary structure in sequences flanking the start codon.
