Description
The plasmid we designed is a modification of the pBBR1MCS-5 , this broad-host-range (bhr) vector has been designed to assist the genetic analysis in prokaryotes, specifically in Gram- bacteria that are naturally CmR (chloramphenicol resistant).
The pBBR1MCS-5 vector is relatively small (4768bp), it has an extended multiple cloning site (MCS) with 15 different restriction sites and it possesses a gentamicin resistance gene. After modification, only 3 of the 15 retrictions sites are present (see design notes).
The plasmid is mobilizable when the RK2 transfer functions is provided in trans and is compatible with IncP, IncQ and IncW group plasmids, as well as with ColE1- and P15a-based replicons.
We used this plasmid to transfer genes from E. coli to R. etli. First we transformed E. coli S17 with this vector containing the genes or sequences that we wanted to transfer, then we did a conjugation between our transformed E. coli cells and Rhizobium etli CFN42
Notes
It was amplified the BBa_J04450 including the prefix and the suffix from the psb1t3 plasmid and adding apaI and sacI restriction sites at the ends of the sequence. After, a ligation by sticky ends was with the pBBR1MCS-5 the apaI and sacI enzimes, trying to eliminate as mouch as possible of the MCS??? restriction sites
We use the sequence as reported by Kovach et al. (1995).
