TABLE 1.

Predicted and observed molecular masses and serine-and-threonine contents of ehrlichial glycoproteins and repeat regions

Protein	Molecular mass (kDa)		Ser/Thr content (n/%)
	Predicted	Observeda	Entire open reading frame	Repeat region
E. chaffeensis P120	61	100/120	91/16	70/20
E. canis P140	73	112b/140	147/21	126/25
HGE agent P100	61	100/NDc	65/11	30/11
HGE agent P130	66	130/ND	156/25	80/30

^aThe first value is for the recombinant expressed as detected by immunoblotting; the second value is for the native protein. 

^bFourteen-repeat region (78% of the open reading frame). 

^cND, no data.
