    2.7.1.60 | ManNAc kinase in complex with its substrate ManNAc, its product ManNAc 6-phosphate, with or without ADP, vapor diffusion at 18°C, mixing 0.002 ml of 15 mg/ml protein in 10 mM Tris-HCl, pH 8.0, 150 mM NaCl, and 2 mM ManNAc, with 0.002 ml of reservoir solution containing 0.2 M calcium acetate, 0.1 M sodiumcacodylate, pH 6.5, and 40% PEG 300, 5 days, X-ray diffraction structure determination and analysis at 1.64-2.10 A resolution. No crystals by co-crystallization of hMNK with ManNAc and ADP, ATP, AMPPCP, or AMPPNP, but ternary complexes are obtained by soaking crystals of the binary hMNK-ManNAc complex replacing stepwise their mother liquor with solutions containing 0.1 M sodium cacodylate, pH 6.5, 50% PEG 300, and 20 mM ADPor ATP or nonhydrolyzable ATP derivatives |
