Part:pSB3K3

Low to medium copy BioBrick standard vector

pSB3K3-1 is a medium copy plasmid with kanamycin resistance. It has a p15A pMR101-derived replication origin, copy number 20-30. (Lutz and Bujard, 1997) pSB3K3-1 has a terminator upstream of its MCS, which is oriented to prevent transcription from *inside* the MCS from reading out into the vectorl. A second terminator (E.coli His operon-derived) is downstream of the MCS, again insulating the vector from transcription reading out of the MCS. Ideally, future versions of standard biobrick vectors would have terminators bracketing the MCS that were 100% efficient in terminating transcription both into and out of the MCS region.
