R462A	modeling of site directed mutagenesis simulations of R462A and R462Q. The energetic profiles for the reaction processes are essentially the same as that in wild type enzyme, but the mutation accelerates the overall enzymatic activity. R462A can reduce the barrier height by about 2.8 kcal/mol. The positive charge on the R462 guanidino side chain group plays a negative role in the catalysis	Streptococcus pneumoniae
