since the km of maltose uptake is altered 10-fold in this mutant and the vmax remains unchanged , it is suggested that the mutation alters the structure of the maltose permease involved in transport of the disaccharide into the cell rather than its regulation.a genetic analysis of the malt1 mutation shows that it is in a gene allelic to one at the mal1 locus .
