Correct enzyme nomenclature
No, not that I have ever seen. Classically, the Enzyme Commission (E.C.) identifiers are the only way to be certain that two (or more) abbreviations or acronyms are all referring to the same enzyme activity. Sometimes, when the situation becomes very complicated interested parties will co-author a proposed new naming convention within their subfield. Some journals may require specific abbreviations, but otherwise authors are free to use whatever nomenclature they like.
