In a scenario, where I have about 25 protein sequences of a lytic enzyme (Variants) of bacterial origin, I would like to estimate the mutational distance of each of these sequences and selecting one of them as baseline I would like to see if the other sequences are its predecessor or successor and estimate their mutational distance from the baseline. Can building a specific phylogenetic tree accomplish the above? If yes, what is the procedure for building such a tree and what tools to use?
