Table VI Average predicted k_{cat}/K_{m} values of our PLS modelThe k_{cat}/K_{m} values for all possible cleavage sequences of P87 [*vs* P87 all] or those except 119 sequences used for the PLS model construction [*vs* P87 unused] were calculated using our PLS model. The average and standard deviation (S.D.) of the *k*_{cat}/K_{m} values for cleaved, uncleaved, and total sequences are shown. The average *k*_{cat}/K_{m} values of the “Cleaved” versus the “Uncleaved” sequences were significantly different (*p* = 5.1×10^{−8} and 4.9×10^{−4}, *t*-test for two population means with unknown and unequal variances).
