Table 4. Pairwise percent amino acid identities between the predicted pigeon picornavirus (PiPV-A/PiPV-B) proteins and the corresponding proteins in different sapeloviruses and enteroviruses.

PiPV-B versus:	L	P1	VP1	VP2	VP3	VP4	P2	2A
DPV	NS	36	27	41	40	42	28	NS
SPV-1	NS	37	30	49	43	41	24	NS
PEV-A	NS	39	31	48	44	39	28	NS
HEV-A	NS	33	27	39	34	36	29	NS
HRV-A	NS	30	21	33	36	35	28	NS
Length of PiPV-B	112	840	306	193	227	114	636	191

Accession numbers of the sequences used for the alignment and calculation of amino acid identities are listed in Table 3. Lengths of proteins as number of amino acids are noted for PiPV-B (and PiPV-A). NS = no significant alignment.
