Conserved Walker A (WA), Walker B (WB) and Lid Subdomain Sequences in Terminase TerL Subunits

Phage	WA Motif	WB Motif	Lid
Lambda	KSA-R⁷⁹-VGYS	VAGYD-E⁷⁹	³²⁷W-D³⁴²-T^364,a
T4	LS-R¹⁶²-QLGKT	MIYID-E²⁵⁶	³¹⁴I-E³⁵¹-E³⁵⁷
P74-26	LG-R³⁹-QSGKS	FVILD-E¹⁵⁰	²²¹S-E²⁴⁷-V²⁵¹
Sf6	GG-R²⁴-GSGKS	ICWVE-E¹¹⁹	¹⁷³N-E¹⁸⁷-A²¹⁰

^aThe sequence associated with the lambda lid subdomain is proposed, based on the lambda structural model (41,72) and published crystal structure data of the other terminase enzymes.
