The presence of open reading frames (ORF) in the metagenomic insert (A) and how they correspond with the arrangement of the β-glucoside utilization pathway from Shewanella amazonensis (B); bglA^I – gene encoding the putative cytoplasmic β-glucosidase, bglT, omp^Bgl – genes encoding the putative β-glucosides transporters, glcP^Bgl – gene encoding the putative β-glucose permease, bglA^II – gene encoding the putative periplasmatic β-glucosidase, glk^II – gene encoding the putative ROK-type glucokinase, lamA – gene encoding the extracellular β-glucanase, bglR – gene encoding the putative novel LacI-type transcriptional regulator; the black circles represent the predicted binding sequences for the putative transcriptional regulators of the Bgl utilization pathway (Rodionov D.A. et al. 2010).
