This work demonstrates the feasibility of using Raman spectroscopy for the analysis of small quantities of chemically similar oligosaccharides and their mixtures. Raman spectra were obtained from 10-microL aliquots of 1 mM solutions of maltotetraose and/or stachyose after deposition onto

In Part 2 of this series of DFT optimization studies of alpha-maltotetraose, we present results at the B3LYP/6-311++G** level of theory for conformations denoted 'band-flips' and 'kinks'. Recent experimental X-ray studies have found examples of amylose fragments with conformations distorted

Analysis of the genome sequence of Caulobacter crescentus predicts 67 TonB-dependent outer membrane proteins. To demonstrate that among them are proteins that transport nutrients other than chelated Fe(3+) and vitamin B(12)-the substrates hitherto known to be transported by TonB-dependent transporters-the

Study of the maltose/maltodextrin binding protein MalE in Escherichia coli has resulted in fundamental insights into the molecular mechanisms of microbial transport. Whether gram-positive bacteria employ a similar pathway for maltodextrin transport is unclear. The maltodextrin binding protein MalE has

Glucose and maltose esters were synthesised in organic media by employing a lipase (E.C. 3.1.1.3) from Candida antarctica. In a second reaction step, a transglycosylation catalysed by a cyclodextrin glycosyltransferase (E.C. 2.4.1.19) from either Paenibacillus sp. F8 or Bacillus sp.
