10220355-4	1999	In this paper, we report that several divalent metal cations, such as Mn2+, Co2+, Ni2+, and Zn2+ bind to the second Mg2+-binding site of Csk with up to 13200-fold higher affinity than Mg2+.	Manganese(2+)	70-74	C-terminal Src kinase	Homo sapiens	137-140	
10220355-6	1999	Substitution by these divalent metal cations resulted in varied levels of Csk activity, with Mn2+ even more effective than Mg2+.	Manganese(2+)	93-97	C-terminal Src kinase	Homo sapiens	74-77
