a, according to Horn et al. [14];
b, positive strand (cooriented as the majority of the genes of the GI); gly-tRNAs are separated by 88 nt;
c, identified by BLAST [35; 36] and CLUSTALW [39] by ourselves;
d, phage-related protein based on additional BLAST hit;
e, partially annotated by Horn et al. [14] and further characterized by ourselves by BLAST [35, 36].
