Table 2 Number of protein-protein interactions for the different classes.

Interaction		Ribosomal	Operon	Non-operon
		(45/43/43)	(73/45/29)	(86/62/52)
Ribosomal	MINT db	54 (57)	138	363
	Permutation	121.7 (120.1)	97.1 (111.9)	245.3 (242.3)
	P-value	1.0 (1.0)	0 (0)	0 (0)
Operon	MINT db		20 (62)	56
	Permutation		16.9 (26.0)	94.2 (112.8)
	P-value		0 (0)	1.0 (1.0)
Non-operon	MINT db			57 (110)
	Permutation			112.8 (121.7)
	P-value			1.0 (0.95)

The numbers shown are for all pairs of persistent genes found in MINT, both without (and with) self interactions included. The table also shows the average number of protein-protein interactions after 10,000 permutations, and estimated p-values for getting a number of interactions after permutation that is larger than the experimental one. The number of genes of each class in the full set, represented in MINT and found as interaction pairs in MINT is shown in the table header.
