Native structure of chimaeric amylase from B. amyloliquefaciens and B. licheniformis at 1.92A
Crystallization Crystalization Experiments ID Method pH Temperature Details 1 VAPOR DIFFUSION, HANGING DROP 7.5 291 CRYSTALS WERE GROWN AT 18C USING THE HANGING DROP METHOD WITH 8-13% MONOMETHYL ETHER POLYETHYLENE GLYCOL 2000 OR 5000 AS PRECIPITANT. DROPS WERE BUFFERED WITH 0.1M TRIS/HCL PH 7.5 CONTAINING 5MM CACL2 AND THE PROTEIN CONCENTRATION WAS 30-35MG/ML.
