Purification, crystallization and preliminary crystallographic analysis of the CBS-domain protein MJ1004 from Methanocaldococcus jannaschii.


ABSTRACT: The purification and preliminary crystallographic analysis of the archaeal CBS-domain protein MJ1004 from Methanocaldococcus jannaschii are described. The native protein was overexpressed, purified and crystallized in the monoclinic space group P2(1), with unit-cell parameters a=54.4, b=53.8, c=82.6?Å, ?=106.1°. The crystals diffracted X-rays to 2.7?Å resolution using synchrotron radiation. Matthews-volume calculations suggested the presence of two molecules in the asymmetric unit that are likely to correspond to a dimeric species, which is also observed in solution.
