Abstract Amino acid composition and electrophoretic mobility suggest that two polymorphic proteins in human parotid saliva, Pm and PmS, are basic proline-rich proteins. Comparison of two basic proline-rich proteins previously isolated by D. L. Kauffman and P. J. Keller (1979) [Arch. Oral. Biol. 24: 249], IB-6 and IB-9, with PmS and Pm demonstrated corresponding electrophoretic mobilities on cationic polyacrylamide slab gels. Further, the amino acid compositions of IB-9 and Pm were found to be similar. Although differences in amino acid composition and carbohydrate content were noted, such differences could be accounted for, suggesting that IB-9 and Pm are identical.
