What is the restriction site for BamHI?

Restriction Enzyme Cut Site: G/GATCC.

What is the source of BamHI restriction enzyme?

BamHI is a type II restriction enzyme derived from Bacillus amyloliquefaciens. Like all Type II restriction endonucleases, it is a dimer and the recognition site is palindromic and 6 bases in length.

Where are restriction sites located?

Restriction sites, or restriction recognition sites, are located on a DNA molecule containing specific (4-8 base pairs in length) sequences of nucleotides, which are recognized by restriction enzymes.

What is the structure of BamHI in unbound form?

In its unbound form, BamHI displays a central b sheet, which resides in between α-helices. BamHI undergoes a series of unconventional conformational changes upon DNA recognition. This allows the DNA to maintain its normal B-DNA conformation without distorting to facilitate enzyme binding. BamHI is a symmetric dimer.

Where can I find more details about BSA-free versions of BamHI?

Find more details at www.neb.com/BSA-free. BamHI has a High Fidelity version BamHI-HF ® ( NEB #R3136 ). High Fidelity (HF) Restriction Enzymes have 100% activity in rCutSmart Buffer; single-buffer simplicity means more straightforward and streamlined sample processing.

What are the active site residues of the ionic compound BamHI?

BamHI has three critical active site residues that are important for metal catalyst. They are known as Asp94, Glu111 and Glu113. These residues are usually acidic. In the presence of a metal ion, the residues are pointed toward the metal ion. In the absence of metal ions, the residues are pointed outward.

What is a unit of BamHI?

A E. coli strain that carries the BamHI gene from Bacillus amyloliquefaciens H (ATCC 49763). One unit is defined as the amount of BamHI required to digest 1 µg of λ DNA in 1 hour at 37°C in a total reaction volume of 50 µl..
