What structural features do you know that may lead to the existence of tautomers?

keto-enol tautomers, but I don't how and where proton transfer. I'm not chemist at all.

Are you referring to this compound?

http://en.wikipedia.org/wiki/File:Mycosporine-2-glycine.svg

If so, the tautomer would be formed by protonating the upper nitrogen, deprotonating the lower nitrogen, and moving the double bonds appropriately.
