TABLE 1.

Major characteristics of PTP1 and PTP2 from E. cuniculi, E. intestinalis, and E. hellem^a

Protein	Total aa	pI	%			C-terminal residue	Presence of tandem repeats (20–28 aa)	No. of N-glycosylation sites
Protein	Total aa	pI	Pro	Lys	Cys	C-terminal residue	Presence of tandem repeats (20–28 aa)	No. of N-glycosylation sites
EcPTP1	395	4.9	13.4	1.6	4.6	C	+	3
EiPTP1	371	4.9	12.9	2.7	4.6	C	+	0
EhPTP1	453	4.9	14.6	1.4	4.9	C	+	9
EcPTP2	277	8.6	5.4	11.6	2.9	E	−	1
EiPTP2	275	8.6	5.5	11.3	2.9	E	−	2
EhPTP2	272	8.6	5.5	10.3	2.9	E	−	1

Data for EcPTP1 (11) and EhPTP1 (21) have been reported previously. Proline and lysine are the most abundant amino acids in PTP1 and PTP2, respectively.
