Figure 4From: Differential proteomic profiling reveals regulatory proteins and novel links between primary metabolism and spinosad production in Saccharopolyspora spinosa Overall illustration of global regulators between primary metabolism and secondary metabolism in S. spinosa . Enzymes were underlined when the total PAI value more than 3 which revealed it is a abundant protein in S. spinosa proteome. Black dot indicated a enzyme owned a peak in T2 when compared to other three phases. Enzyme name abbreviations refer to Additional file 3: Table S5.Back to article page
