Hi netters!

I would like to make a constitutive active mutant of a protein which
is activared by tyrosine phosphorylation.

I am thinking of substituting the the tyrosine residue by aspartic
acid. Is aspartic acid mimicking phosphotyrosine?

Are there any references?

Any hint will be appreciated,
