Abstract
Attempts were made to determine the position of the portion on the structure gene for amylase specifying the electrophoretic characteristics of amylase-4, amylase-1088 and amylase-1 produced by different strains of Bacillus subtilis. The results showed that each of amy4, amy1088 and amy1, which were allelic to each other, might have respectively a portion, namely E4, E1088 and E1, locating at a definite position between O5 and A4, and specifying the electrophoretic characteristics of each amylase protein. Data were obtained which showed that E might occupy a certain length on the structure gene.
