Dear Dr. Spirov:
Many people have analyzed very different protein families with one another
to look at the rate of replacement of individual amino acids, in what
contexts are amino acids replaced by one another, what is the relationship
between motifs in primary structure with secondary and tertiary structure,
which sequences are more or less susceptible to metabolic degradation and
post-translational modification, etc. In addition, many investigators have
been interested in questions involving information theoretic and fractal
analyses of sequences in order to understand the efiicency and accuracy of
coding and the potentiality of long range interactions.
I hope that some of these suggestions may be of interest to you.
Sincerely,
John
