BstYI
R▾GATCY5′ overhang (4)
BstYI is a 6 bp-recognition restriction enzyme. It runs best in rCutSmart at 60°C.

RGATCY (degenerate). Incubate at 60°C. Not heat-inactivable. Despite the GATC core, NEB reports Dam not sensitive (unlike MboI).

Frequently asked questions
What does BstYI recognize?
BstYI recognizes the 6 bp sequence RGATCY (5′→3′), cutting the top strand between position 1 and 2 within the site to leave a 5′ overhang of 4 bases.
What buffer should I use for BstYI?
rCutSmart gives the highest activity (incubate at 60°C). Supplied NEBuffer 2; rCutSmart 100% too.
Does BstYI have star activity?
No documented star activity under standard reaction conditions.
Is BstYI blocked by DNA methylation?
Not blocked by Dam, Dcm, or CpG methylation.
Can I heat-inactivate BstYI?
No — BstYI is not heat-inactivable. Use a column cleanup or phenol-chloroform extraction to stop the reaction instead.
