It's been a while since I've had to consider such distributions. Many folks like the following text for sequence-related problems: Biological sequence analysis: probabilistic models of proteins and nucleic acids By Richard Durbin - Cambridge University Press (1998) - Paperback - 356 pages - ISBN 0521629713 Give it a shot & good luck!
