Table 2. Summary of the UV/VIS spectroscopic experiments on EBV R2 in comparison with similar studies performed on other R2s.

	Bathophenanthroline-sulphonate	Catechol
EBV R2	+	++
E. coli R2 [56]	−	−
Mouse R2 [55], [56]	+++	+++
HSV2 R2 [28]	n/a	++

The extent of the reactions was evaluated semi-quantitatively. The symbols indicate (+) positive reaction and (−) no reaction.
