'''Crystal structure of scytalone dehydratase F162A mutant in the unligated state'''<br />


==Overview==
==Crystal structure of scytalone dehydratase F162A mutant in the unligated state==
Scytalone dehydratase variant F162A, in which Phe162 in the C-terminal, region was replaced with alanine, was crystallized with polyethylene, glycol 4000. Because the crystal was radiation-sensitive, the diffraction, data were collected at cryogenic temperatures. The crystal belonged to, monoclinic space group P2(1), with unit-cell parameters a = 72.64, b =, 61.30, c = 72.62 A, beta = 120.02 degrees at 37 K. The calculated V(M), value was acceptable when a trimer of the mutant enzyme occupied a, crystallographic asymmetric unit. The resolution limit was extended to, 1.45 A at BL41XU of SPring-8 at 37 K.

== Publication Abstract from PubMed ==
Scytalone dehydratase variant F162A, in which Phe162 in the C-terminal region was replaced with alanine, was crystallized with polyethylene glycol 4000. Because the crystal was radiation-sensitive, the diffraction data were collected at cryogenic temperatures. The crystal belonged to monoclinic space group P2(1), with unit-cell parameters a = 72.64, b = 61.30, c = 72.62 A, beta = 120.02 degrees at 37 K. The calculated V(M) value was acceptable when a trimer of the mutant enzyme occupied a crystallographic asymmetric unit. The resolution limit was extended to 1.45 A at BL41XU of SPring-8 at 37 K.
