2.1.1.10	Cd2+	activating	441385	
2.1.1.10	Cd2+	can replace Zn2+	441389	
2.1.1.10	additional information	contains a zinc-binding motif, no stimulation by 0.1 or 1 mM Zn2+	441387	
2.1.1.10	additional information	contrary to human enzyme, K+ is not required	733308	
2.1.1.10	Zn2+	activating	441385	
2.1.1.10	Zn2+	required for activity	441389, 687808	
2.1.1.10	Zn2+	required. The metallated crystal form has residues C229, C295 and C296 coordinated to a Zn2+ center. the coordination of homocysteine to metal with a distance of 2.8 A contributes to near-ideal Zn2+-centered tetrahedron geometry	733308
