Number of accessory genes and reactions across all strain-specific GEMs

	Genes		Reactions
Occurrence (in %)	Mean	Standard deviation	Mean	Standard deviation
[1–20]	1.9	1.8	4.7	7.7
[21–40]	6.9	2.5	1.3	1.2
[41–60]	16.7	3.2	17.4	6.0
[61–80]	17.8	2.4	20.2	6.3
[81–99]	296.9	8.1	219.3	6.8

Based on 338 accessory reactions, we categorized accessory genes and reactions by percentage of occurrence across all strain-specific GEMs. For each range of percent (e.g., 1–20% of strains), we show the predicted mean number of genes and reactions, with standard deviations.
