last month I have joined the Editorial Board of the International Journal of Molecular Sciences. I would like to invite interested colleagues to join me in stressing the role of isotope effects in studies of enzymatic reactions by submitting an article to the special issue on this subject – banner attached. More detailed information is available at the IJMS website ( IJMS | Special Issue : Research on the Application of Isotope Effect in Enzymatic Reaction (mdpi.com)) or directly from me.
