Characterization of the L-malate permease gene (maeP) of Streptococcus bovis ATCC 15352.

摘要

A gene which was shown to be cotranscribed with the NAD+-dependent malic enzyme gene (maeE) of Streptococcus bovis ATCC 15352 was revealed to encode L-malate-specific permease (MaeP), which showed high activity at low pHs (pH 5.1 to 5.9). MaeP was strongly inhibited by the ionophores nigericin and valinomycin.
