Prevotella loescheii PK1295 produces at least 3 proteases that are separable by isoelectric focusing. One of these proteases, an enzyme with an isoelectric point at 8.5 and an M(r) of 36,000, hydrolyzes the fimbria-associated adhesin on P. loescheii responsible for coaggregation with Streptococcus oralis 34, as well as gelatin, casein and fibrin. The action of this protease may contribute to the detachment of P. loescheii from its streptococcal coaggregation partner and provide a mechanism for bacterial relocation in dental plaque.
