Beta-glucosidase A from Thermatoga maritima (bglA)

bglA gene which encodes the Beta-glucosidase A from thermophile Thermotoga maritima. Translated protein has a mass of 52kDa. The protein contains a triple salt bridge motif which makes it highly thermostable.

Usage and Biology

The Thermatoga maritima Beta-glucosidase A enzyme expresses well under the T7 promoter in a pET28a, even without IPTG induction, due to a leaky promoter. The protein is mostly soluble based on small scale expression tests and runs at ~55 kDa on an SDS-Page gel.

Figure 1. Soluble expression for the wild-type protein, the pET28a vector was known to have a leaky promoter so the bands at ~55kDa (expected mass 52kDa) indicate expression, as they are absent in lanes used for mOrange and Antibody expression (lanes 2-10).
