Gene Expression and Protein Synthesis of Esterase from Streptococcus mutans are affected by Biodegradation By-product from Methacrylate Resin Composites and Adhesives

摘要

An esterase from S. mutans UA159, SMU_118c, was shown to hydrolyze methacrylate resin-based dental monomers.Objective:To investigate the association of SMU_118c to the whole cellular hydrolytic activity of S. mutans toward polymerized resin composites, and to examine how the bacterium adapts its hydrolytic activity in response to environmental stresses triggered by the presence of a resin composites and adhesives biodegradation by-product (BBP).
