Abstract

The S. mutans GBP-A is hypothesized to be constitutively expressed and to contribute to the sucrose-dependent colonization of S. mutans. To investigate GBP-A expression, a reporter gene encoding chloramphenicol acetyltransferase ( CAT) was placed downstream of the gbpA promoter and CAT activity was measured under conditions that would be associated with the sucrose-dependent colonization of S. mutans. Expression of GBP-A was optimal under anaerobiosis and neutral pH conditions, and correlated with optimal growth. The addition of sucrose to the growth medium did not elevate the expression of GBP-A.
