how to model methylation reactions?

[egonw]

I was look at @fehrhart's WP4673 and a "possible mim-translocation" curation event (false positive) on these interactions:

I understand these as methylation reactions. What is the correct MIM type for these? I do not think we have that in this list of interaction models.

Use ArrowHead="mim-modification" for methylation reactions (as used in WP4673). To eliminate false positives, add mim-modification test cases to WikiPathwaysInteractions/FilesGPML/ following the pattern of existing MIM types like mim-conversion.
