Resolution of space-group ambiguity and structure determination of nodamura virus to 3.3 A resolution from pseudo-R32 (monoclinic) crystals [0.03%]
由伪R32(单斜)晶型解析nodamura病毒空间群并将其结构精修至3.3埃分辨率
A Zlotnick,P Natarajan,S Munshi et al.
A Zlotnick et al.
Monoclinic crystals of nodamura virus (NOV) have two virus molecules per asymmetric unit. Packing analysis reveals a pseudo-rhombohedral (pseudo-C2 monoclinic) arrangement of particles in the actual P2(1) space group (a = 562.1, b = 354.1, ...

G Bujacz et al.
The structure of orthorhombic crystals of monellin, a sweet protein extracted from African serendipity berries, has been solved by molecular replacement and refined to 2.3 A resolution. The final R factor was 0.150 for a model with excellen...
Lysozyme aggregation studied by light scattering. II. Variations of protein concentration [0.03%]
利用光散射研究溶菌酶聚集的第二种方式:蛋白质浓度的变化
Y Georgalis,P Umbach,J Raptis et al.
Y Georgalis et al.
Static and dynamic light scattering have been employed to investigate the behaviour of nucleating lysozyme solutions in the range between 0.34 and 3.08 mM. Preselected concentrations of NaC1 and (NH(4))(2)SO(4) have been used to screen the ...

Y Georgalis et al.
Static and dynamic light scattering have been employed to investigate the behaviour of lysozyme solutions when varying the concentration of (NH(4))(2)SO(4) and NaCl for screening the repulsive forces between the monomers. At the initial agg...
Experiences from the structure determination of human cytomegalovirus protease [0.03%]
人巨细胞病毒蛋白酶结构测定的体会
L Tong,C Qian,W Davidson et al.
L Tong et al.
Several obstacles were encountered and overcome during the structure determination of human cytomegalovirus protease. Dehydration of crystals, by exposing them to higher concentrations of the precipitant, reduced the mosaicity of the crysta...
New techniques for applying anomalous-scattering and isomorphous-replacement data incorporated in ANOMIR - a general application package [0.03%]
应用于ANOMIR的异常散射和同晶置换数据诠释的新技术——一个通用软件包
