RBS + bglX (E. coli perisplasmic β-glucosidase)

This is the E. coli β-glucosidase gene bglX. The part contains the native Ribosome Binding Site.

The part was made using the strategy outlined in BBa_K523000, and therefore contains 4 extra bases at the 5' end which generate a BglII restriction site.

Usage and Biology

The product protein is believed to be periplasmic. Beta-glucosidase cleaves β(1→4) bonds, i.e. those found in the disaccharide cellobiose.

The SignalP program predicts that a 20 amino acid localisation signal (at the N terminal) is cleaved off before the protein reaches its mature form.

Edinburgh 2011 carried out some experiments on this part under the control of the lac promoter - see details at part BBa_K523014.
