Summary of capsid association of DNA cleavage and packaging proteins

Virus type	Capsid or virion	Signal strength of DNA cleavage and packaging proteina:
		UL6	UL15 (81 kDa)	UL15 (87 kDa)	UL25	UL28
Wild type	B	+++	++	+	+++	++
Wild type	C	+++	+b	++	+++	−
UL6 mutant	B	−	+b	−	+++	++
UL15 mutant	B	+++	−	−	+++	++
UL25 mutant	A	+++	+++	+	−	+++
UL25 mutant	B	+++	+++	+	−	+++
UL28 mutant	B	+++	+b	−	+++	−
UL32 mutant	B	+++	++	+	+++	++
Wild type	Virion	NDc	+/−	+++	ND	ND

^a+++, ++, +, +/−, and − indicate the relative strength of the signal detected on the immunoblots shown in Fig. 3A, 6A, 7A, 8A, 9A, and 10A. 

^bThe 81-kDa UL15 band was detected throughout the gradient. 

^cND, not determined.
