The Bacillus megaterium expression system provides a versatile and easy-to-handle tool for stable and high-yield protein production, both small- and large-scale. 
Several vectors are available as positive controls for expression in B. megaterium. pGFP1522 (BMEG10C) expresses GFP under the control of xylose inducible PxylA promoter. pRBBm15C (BMEG13C), pRBBm13C (BMEG14C) and pRBBm16C (BMEG15C) encode mutant proteins of levansucrase, an enzyme of Lactobacillus reuteri.
These three vectors have been validated for recombinant production and one-step affinity purification of L. reuteri levansucrase from growth medium using a B. megaterium expression system. Click here for background information regarding the controls. 
  • pGFP1522 (BMEG10C) - expresses GFP under the control of xylose inducible PxylA promoter
  • pRBBm15C (BMEG13C) - encodes protein of levansucrase, HIS-Tag
  • pRBBm13C (BMEG14C) - encodes protein of levansucrase, STREP-Tag
  • pRBBm16C (BMEG15C) - encodes protein of levansucrase, STREPHIS-Tag
Please note positive control vectors are available only in combination with a regular B. megaterium expression vector.
