Table 1.

Amino acid frequencies in left or right APD tails of H. sapiens divided by their corresponding frequency in the whole proteome

	A	C	D	E	F	G	H	I	K	L
Left/total	1.1	0.2	0.4	0.5	0.4	1.3	1.6	0.5	2.1	0.5
Right/total	0.7	2.4	0.8	0.7	2.7	0.6	0.5	1.6	0.3	1.8
	M	N	P	Q	R	S	T	V	W	Y
Left/total	0.4	0.2	3.3	0.3	2.8	0.6	0.5	0.7	0.4	0.1
Right/total	0.8	1.5	0.2	1.2	0.2	0.7	0.8	1.2	0.8	2.7

Values exceeding 1.0 are shown in bold. Similar frequencies were found for all the proteomes.
