Table 5. Relative expression changes in polyamine biosynthesis genes in S. Pneumoniae TIGR4 ΔpotABCD compared to WT TIGR4.

Gene	Description	∆potABCD/TIGR4 (Fold Change)	p-value
speE	Spermidine synthase	14.4	1.81E-12
cad	Lysine decarboxylase	17	5.98E-12

P-values were calculated using paired two-tailed t-test.
