Zj. Fu et al., CRYSTALLIZATION AND PRELIMINARY-X-RAY DIFFRACTION STUDIES OF GLYCINE METHYLTRANSFERASE FROM RAT-LIVER, Journal of structural biology, 113(3), 1994, pp. 247-249
Glycine methyltransferase from rat liver is a tetrameric enzyme with 2
92 amino acid residues in each identical subunit and catalyzes the Ado
Met-dependent methylation of glycine to form sarcosine. The enzyme was
crystallized by the hanging drop vapor diffusion method, using polyet
hylene glycol 4000 as a precipitant. The crystal belongs to the orthor
hombic space group P2(1)2(1)2, with unit cell dimensions of a = 86.4,
b = 175.7, c = 45.5 Angstrom and with two subunits in the asymmetric u
nit. The crystals diffract beyond 2.4 Angstrom resolution, and a set o
f 2.4 Angstrom resolution data were measured. (C) 1994 Academic Press,
