Table 2 The difference in characteristics of 5'-end proximal hairpins started in 6^th – 20^th CDS positions of human and mouse cDNAs characterized by optimal and suboptimal start codon contexts (purine (Pu) and pyrimidine (Py) in pos. -3 upstream AUG, respectively; E_tot, energy of an eligible hairpin, kcal/mol; E_st, energy of the hairpin stem region, kcal/mol; L_st, size of the hairpin stem region, base pairs)†
