Search and Convert case of certain part of the word

[laith93]

Hello, forums members,



I have gene names with special styles (fyuA, fimH ..etc)

so how to search and replace for gene names that had been written in this format (fyuA, fimH) to this format (fyuA, fimH ..etc).

I can't search for just fyu or fim, because I have other words with the same prefix, hence to prevent misreplace.

Thank you
