... enzyme. For example, the first three digits of the EC number for PA1589 (EC 6.2.1.5) are the same as those for the missing enzyme (EC 6.2.1.6), therefore we predicted that PA1589 is a candidate for ... incorporation of directed information of genes into the similarity would be interesting. For phylo- genetic profiles, the use of a real-valued phylogenetic profile [36] might imp...
