Design Notes

The gene was amplified by PCR from Bacillus subtilis strain 168, which has the ATCC6051 genome that is the same strain as NCCB 70064, also same as KTCC 1028. Mini-3 amino acid sequence was retrieved from UniProt (UniProt ID: O31418), introduced as a query in tBlastn from NCBI against B. subtilis ATCC 6051 genome and the resulting mini3 sequence (GenBank: CP011115.1) was used as a template for the design of the primers. Primers were designed to have a melting temperature of 59-60 ºC. Overhangs with BglBricks Prefix and Suffix were added, along with a His-tag in the Reverse primer for a C-terminal-tagged protein. Designed to be cloned through Gibson Assembly. The primers used were the following:

Source

Genomic DNA from B. subtilis strain 168. Plasmid used pBbE8c backbone from BglBricks. pBbE8c-RFP was a gift from Jay Keasling (Addgene plasmid # 35269; http://n2t.net/addgene:35269; RRID:Addgene_35269) [1] Please refer to the Addgene page for more information about licences associated with the use of the plasmid.
