Abstract

We determined the amino terminal sequence of rat and human vitamin D binding protein (VDBP). The sequences of the two proteins are: Rat VDBP: LeuGluArgGlyArgAspTyrGluLysAspLysValCysGlnGluLeuSerThrLeuGlyLys Human VDBP: LeuGluArgGlyArgAspTyrGluLysAsnLysValCysLysGluPheSerHisLeuGlyLys AspAspPhe GluAspPhe. There are 19 matches out of a total of 24 residues sequenced giving a percent match/lenght of 79.2%. Differences in the composition of the two proteins at residue 10, 14, 16, and 22 can be accounted for by single base changes in the the gene for the proteins. The difference (Thr→His) at residue 18 requires a change in two bases in the respective genes. We conclude that the sequence of the amino terminus of rat and human VDBP is similar with a high degree of homology between the two proteins.
