摘要
The DNA methyltransferase M.BseC1 from B. stearothermophilus methylates the N6 atom of the 3' adenine in the sequence 5'-ATCGAT-3'. The 579-residue protein has been isolated and crystallized using seeding and microdialysis techniques. The crystals are monoclinic, space group P2(1) with cell dimensions a = 53.7, b = 85.7, c = 1518 Angstrom and beta = 95.1 degrees, two molecules in the asymmetric unit and diffract to at least 2.5 Angstrom resolution.
