OtsB: Part 2 of 2 coding for trehalose producing enzymes
Sequence codes for trehalose phosphatase enzyme. This enzyme is the second of two required for the conversion of glucose to trehalose.
This enzyme catalyses the following reaction:
alpha,alpha-trehalose 6-phosphate + H2O -> alpha,alpha-trehalose + phosphate
Trehalose is a disaccharide formed from two glucose molecules. Throughout nature, trehalose is associated with resistance to dessication and cold shock otsb1, and is naturally produced in Escherichia Coli. We hope that by upregulating the trehalose production pathways in E.coli we can increase trehalose concentrations within our cell, thereby conferring some resistance to protein degredation in our system. This would allow easy transport and storage of the final product.

Design Notes
PCR from Escherichia Coli using BL21(DE3) as the genomic DNA template and the Pfu Ultra II enzyme. Primers were designed to include overhangs coding for XbaI and SpeI recognition sites in order to allow the gene to be BioBricked according to the BioBrick Standard. The primers are as follows:
Forward PCR primer containing XbaI overhang (bold) for BioBricking:
GCTCTAGATGACAGAACCGTTAACCG
Recomended Temperatures for PCR : 54.5C(without overhang) and 64.8C(with overhang)
Reverse PCR primer containing SpeI overhang (bold) for BioBricking:
GGACTAGTATTAGATACTACGACTAAACGAC
Recomended Temperatures for PCR : 54.7C(without overhang) and 64.2C(with overhang)
