S. Kawai et al., CHARACTERIZATION OF THE L-MALATE PERMEASE GENE (MAEP) OF STREPTOCOCCUS-BOVIS ATCC-15352, Journal of bacteriology, 179(12), 1997, pp. 4056-4060
A gene which was shown to be cotranscribed with the NAD(+)-dependent m
alic enzyme gene (maeE) of Streptoccus bovis ATCC 15352 was revealed t
o 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 ionoph
ores nigericin and valinomycin.
