A very good reference is this:
@ARTICLE{MuellerV00,
author = {Tobias M{\"u}ller and Martin Vingron},
title = {Modeling Amino Acid Replacement},
journal = JCB,
year = {2000},
volume = {7},
pages = {761--776},
number = {6},
}
JCB is Journal of Computational Biology. The rate matrix for the VT
series of matrices is provided. Not strictly PAM, though.
HTH,
