Crystallization (Commentary)

Crystallization (Comment) Organism
X-ray crystal structure of dimeric His6 tagged enzyme is determined to 2.55 A resolution by Multiwavelength Anomalous Dispersion Bacillus subtilis

Metals/Ions

Metals/Ions Comment Organism Structure
Mg2+ Mg2+ provides key contacts with the substrate 6-carboxy-5,6,7,8-tetrahydropterin and the product 7-carboxy-7-carbaguanine, thus anchoring the molecules in the active site. The formation of either 6-carboxypterin product is not enhanced by the presence of Mg2+ Bacillus subtilis

6-carboxypterin under reducing conditions that would promote the reductive cleavage of S-adenosyl-L-methionine, 6-carboxypterin is turned over to 6-deoxyadenosylpterin, presumably by radical addition of the 5'-deoxyadenosine followed by oxidative decarboxylation to the product. In the absence of the strong reductant, dithionite, the carboxylate of 6-carboxypterin is esterified to generate 6-carboxypterin-5'-deoxyadenosyl ester Bacillus subtilis ?
