A methodology for the pharmacodynamical assay of mixtures of 2 spasmogenic peptides is described, illustrated and discussed, with reference to a method intended for the chemists (P. Job, 1927). This allows a quick appreciation of the existence of synergism, of
The multiple-sugar metabolism (msm) locus of Streptococcus mutans constitutes a non-PTS sugar uptake system responsible for the transport and utilization of raffinose, melibiose and isomaltotrioses. While previous studies have used polar mutations to suggest that these genes are co-transcribed, there

An isomaltotriose-producing endo-dextranase was simply purified from cell-free culture broth of a Fusarium sp. by ethanol fractionation and consecutive column chromatographies using DEAE-Toyopearl and Bio-Gel P-100. The purified enzyme was judged to be homogeneous on PAGE and SDS-PAGE as well

An 11-kilobase gene region of Streptococcus mutans has been identified which contains eight contiguous genes involved with the uptake and metabolism of multiple sugars (the msm system). Sequence analysis of this region indicates that several of these genes specify proteins
