LPH was firstly labeled with fluorescein Cy3 using Cy3 Conjugation Kit (Abcam). 3c). The genes flanking the gene locus of LPH were also conserved in these Lactobacillus species, indicating the similar function of these enzymes. Lytic enzymes are necessary for invasion because cancer cells have to penetrate through the extracellular matrix after leaving their tissue of origin. Fewer sequence homologies are shared at the predicted cap domain substrate recognition loop 5, responsible for the chemical diversification within the family, apart from the stringently conserved loop marker Gly (G), flanked by Lys/Arg (K/R) and residues, whose side chains contribute to the catalytic site, probably operating in domaindomain binding, active-site desolvation and/or catalysis (Lahiri et al.
