Unit definition One unit is defined as the amount of enzyme required to hydrolyse completely a unique 5`-G(5mC)G(5mC)-3`/3`-(5mC)G(5mC)G-5` site in 1 μg of pHspAI2 plasmid DNA, which is linearized with GsaI, in 1 hour at 30°C in a total reaction volume of 50 μl. As a result of this site hydrolysis two main DNA fragments (3,419 and 699 bp) are produced (see lanes 3-5 in the figure). GlaI digestion of recognition sequences with three and two 5-methylcytosines results in additional bands appearance (lane 6 in the figure). GlaI activity assay on DNA pHspAI2/GsaI Lanes: 2 Control pHspAI2/GsaI DNA 3 - 0.5 μl GlaI (diluted 1/100), 4 - 1 μl GlaI (diluted 1/100), 5 - 2 μl GlaI (diluted 1/100), 6 - 1 μl of undiluted GlaI, 1 and 7- 1 Kb SE DNA Ladder.Products were separated in 1% agarose gel in TAE Buffer. In the presence of 20% DMSO, the enzyme's activity significantly increases without losing specificity
Assayed on DNA pHspAI2/GsaI is a linearized plasmid pHspAI2, which carries a gene of DNA-methyltransferase M.HspAI (recognition sequence 5`-GCGC-3`) and includes a unique GlaI recognition site 5`-G(5mC)G(5mC)-3`/3`-(5mC)G(5mC)G-5` [2].
Storage conditions 10 mM Tris-HCl (pH 7.6); 250 mM NaCl; 0.1 mM EDTA; 7 mM 2-mercaptoethanol; 0,1% Triton X-100, 0.05 mg/ml BSA, 50% glycerol; Store at -20°C.
Ligation
Nonspecific hydrolysis No detectable degradation of 1μg of Lambda DNA was observed after incubation with 100 units of enzyme for 16 hours at 30°C in a total reaction volume of 50 μl.
Methylation sensitivity The enzyme cleaves only C5-methylated DNA and does not cut unmodified DNAand DNA with N4-methylcytosines [1].
Supplied with enzyme 10 X SE-buffer Y, pHspAI2/GsaI DNA
