Bacillus subtilis can utilize maltose and maltodextrins that are derived from polysaccharides, like starch or glycogen. In this work, we show that maltose is taken up by a member of the phosphoenolpyruvate-dependent phosphotransferase system and maltodextrins are taken up by a maltodextrin-specific ABC transporter. Uptake of maltose by the phosphoenolpyruvate-dependent phosphotransferase system...

Complementation and polarity suppression data are interpreted in terms of the genetic structure of the maltose B region. It is proposed that this region comprises two divergent operons. One operon includes malK, a cistron involved in maltose permeation, and lamB the only known cistron specifically involved in lambda receptor synthesis. The other operon includes malJ(1) and malJ(2) which are mos...

The bacterial GlgE pathway is the third known route to glycogen and only one present in mycobacteria. It contributes virulence of Mycobacterium tuberculosis . involvement biosynthesis was discovered twenty years ago when phenotype a temperature-sensitive smegmatis mutation rescued by glgE gene. evidence at time suggested coded for glucanase responsible hydrolysis glycogen, stark contrast with r...

A glucose-negative, maltose-positive strain of group C Neisseria meningitidis was isolated from the blood of a 63-year-old man. Interestingly, maltose degradation was detected by radiometric methods but not by growth methods.

Influence of fructose, sucrose, glucose, sorbitol and maltose carbon sources at various concentrations on rooting and hyperhydricity apple rootstock MM106 was investigated. Type and concentration of sugars had a significant effect on rooting percentage, mean root number, mean root length, hyperhydricity, as well as survival rate. The in vitro cultures produced the higher rooting percentage, mea...

We isolated mutants of Escherichia coli HS4006 containing the melibiose-H(+) symporter (MelY) from Enterobacter cloacae that had enhanced fermentation on 1% maltose MacConkey plates. DNA sequencing revealed three site classes of mutations: L-88-P, L-91-P, and A-182-P. The mutants L-88-P and L-91-P had 3.6- and 5.1-fold greater maltose uptake than the wild type and enhanced apparent affinities f...

The polytopic inner membrane protein MalF is a constituent of the MalFGK(2) maltose transport complex in Escherichia coli. We have studied the biogenesis of MalF using a combination of in vivo and in vitro approaches. MalF is targeted via the SRP pathway to the Sec/YidC insertion site. Despite close proximity of nascent MalF to YidC during insertion, YidC is not required for the insertion of Ma...
