This recognition sequence is asymmetric, so ligating blunt ends
generated by BsrBI will not always regenerate a BsrBI site.
BsrBI is typically used at 37°C, but can be used at temperatures
up to 50°C.

lac operator

The lac repressor binds to the lac operator to inhibit
transcription in E. coli. This inhibition can be
relieved by adding lactose or
isopropyl-β-D-thiogalactopyranoside (IPTG).
