I would not rule out Mg++ ever coordinating with a primary amine, but
it is much rarer than the reports in Mespeus suggest.
Mg++ with arginine:
Mespeus 10 finds 36 examples, but quick inspection of the list shows
that almost all have coordination number

MESPEUS reports, for example, 13 structure where magnesium is
coordinated by a lysine. 7 with arginines and a bunch of asn/gln side
chains as well. It does not prove, of course, th

Hi folks:
Are Mg++ ions ever observed to chelate primary amines?
Are there any examples in crystal structures?
Thanks.
