Comparative Biochemistry of RBP Phylogenetic Considerations

The amino acid compositions reported for RBP preparations purified from these different species are generally quite similar to each other (see Table I). More than 90% of the amino acid sequence of rabbit RBP has been reported (Rask et al., 1981) in preliminary form. Of the 170 positions available for comparison with the sequence of human RBP, 160 were found to be identical. A comparison of the amino-terminal sequences of human and dog RBP, isolated from urine, has also been reported (Poulik et al., 1975). The two sequences were demonstrably different at only 5 of the first 49 amino-terminal positions. The amino-terminal sequence of 29 residues of bovine serum RBP has been reported
