In the presence of an active site ligand (the ALOX15 inhibitor RS7) rabbit ALOX15 was crystalized as heterodimer and the X-ray coordinates of the two monomers within the dimer exhibit subtle structural differences. Using native polyacrylamide electrophoresis, we here observed that highly purified and predominantly monomeric rabbit ALOX15 and human ALOX15B are present in two conformers with distinct electrophoretic mobilities. In silico docking studies, molecular dynamics simulations, site directed mutagenesis experiments and kinetic measurements suggested that in aqueous solutions the two enzymes exhibit motional flexibility, which may impact the enzymatic properties.","https://refubium.fu-berlin.de/handle/fub188/31886||http://dx.doi.org/10.17169/refubium-31618","eng","https://creativecommons.org/licenses/by/4.0/","600 Technik, Medizin, angewandte Wissenschaften::610 Medizin und Gesundheit::610 Medizin und Gesundheit","lipoxygenases||crystal structure||protein–protein interactions||cooperative effects||molecular dynamics","Conformational Heterogeneity and Cooperative Effects of Mammalian ALOX15","Wissenschaftlicher Artikel","open access","3285","10.3390/ijms22063285","International Journal of Molecular Sciences","6","MDPI AG","33807076","22","1422-0067","Charité - Universitätsmedizin Berlin","no"
