Tandem amino acid repeats in the green anole (Anolis carolinensis) and other squamates may have a role in increasing genetic variability

Table 2 Statistics of the commonly found amino acid repeat types in the green anole proteome

AA type	Count	Average length (Maximum length)	Average length of consecutive AA tract (Maximum length)	Average PLP	Number of PLP = 1 (Percentage)	Number of Codons PLP = 1

S	792	10.2 (78)	6.4 (25)	0.35	31 (3.9 %)	AGC (16), TCC (8), AGT (4), TCG (1), TCA (1), TCT (1)

Q	303	10.4 (103)	7.1 (48)	0.51	40 (13.2 %)	CAG (37), CAA (3)
K	242	8.8 (28)	5.8 (11)	0.42	13 (5.4 %)	AAG (10), AAA (3)

All lengths in this table refer to number of amino acid. AA means amino acid. PLP is the proportion of the longest consecutive pure codon run size to the complete repeat size
