Shell script to edit a file

Hello,
I have a big file in wich I would like to rename inside this exactly the string '_ME' and not rename in case we have 'ABC_MELANGE'. Is there a way to do it by using a shell script?
Any tip will be apreciated.

The file is like described bellow, after using command more filename :

Code:
toto test@GR_4||4_35_1_ME||4_35_17
DntowoB.nts
toto test@DT_3||4_35_1_ME||4_35_17
