Description
This part is composed by J23100-B0034-β-glucosidase-B0015. When this part is expressed in bacteria, they become able to metabolize cellobiose converting it in two molecules of glucose.
This part is an improvement of part BBa_K392008 that was used by UNITS_Trieste 2011 Team.
Assembly
This composite part is developed from previous work by UNITS iGEM team 2011 and Edinburgh team 2011. They discovered that BBa_K392008 (Osaka 2010), coding for a Cellumonas fimi β-glucosidase, possess an apparent frameshift near the start of the coding sequence. The coding sequence has now been determined to start from an ATG located 220 bp downstream of the reported one. We therefore decided to correct the Bba_K392008 in order to have the correct coding sequence. In order to do this we made a PCR on Bba_K392008 by using the following primers:β-Glucosidase_Fw
GCATGAATTCGCGGCCGCTTCTAGATGACCACCACGCGCCCCTC
β-Glucosidase_Rev
GCATCTGCAGCGGCCGCTACTAGTATCAGGGCTGGTAGGTCGCGG
Results
The new Cellulomonas fimi β-Glucosidase was sequenced and then assembled in a transcriptional unit together with J23100, B0034 and B0015.E.coli cells expressing the β-Glucosidase were able to grow in M9 minimal medium supplemented with cellobiose 1% as the only C source while E.coli without this composite part are not able to grow.
