Comparison of the amino acid sequences of hemoglobin and myoglobin chains from different species of animals shows that the chains from related species are similar. The number of differences increases with phylogenetically more separated species. On the assumption that proteins evolve at a constant rate, the number of differences between two homologous proteins will be proportional to the time of divergence in evolution of the species. [Pg.98]

A comparison of the two chains of hemoglobin with myoglobin was made by Watson and Kendrew (1961), Braunitzer et al. (1961a, b), Keil and Sorm (1962), and Sorm (1962a, b). Structural relations between cytochrome c and the remaining heme proteins were studied by Sorm (1962c). [Pg.194]

The principal solution of this topical problem, however, may be expected to emerge from a comparison of hemoglobin and myoglobin of the same species. [Pg.197]

Figure 7.5. Comparing the Amino Acid Sequences of Hemoglobin a and myoglobin. (A) A comparison is made by sliding the sequences of the two proteins past one another, one amino acid at a time, and counting the number of amino acid identities between the proteins. (B) The two alignments with the largest number of matches are shown above the graph, which plots the matches as a function of alignment. Figure 7.5.

Construction of an evolutionary tree based on sequence comparisons revealed approximate times for the gene duplication events separating myoglobin and hemoglobin as well as the a and p subunits of hemoglobin. Evolutionary trees based on sequences can be compared to those based on fossil records. [Pg.297]

Anyone aware of the similar biochemical functions of hemoglobin, myoglobin, and leghemoglobin could expect the structural similarities. In a growing number of other cases, however, a comparison of three-dimensional structures has revealed striking similarities between proteins that were not expected to be related. A case in point is the protein actin, a major component of the cytoskeleton (Section 34.2), and heat shock protein 70 (Hsp-70), which assists protein folding inside cells. These two proteins were found to be noticeably similar in structure despite only 1.5.6% sequence identity (Figure 6.15). On the basis of their three-dimensional structures,... [Pg.173]
