Disease relevance of Melezitose

• This group of strains can be easily differentiated from the other Enterococcus species by DNA-DNA hybridization and by their phenotypic characteristics: the strains do not grow in 6.5 % NaCl, and they do not produce acid from L-arabinose, melezitose, melibiose, raffinose or ribose [1].

High impact information on Melezitose

• Exponential-phase cells were suspended in a solution containing 0.5 M melezitose, and their cell walls were hydrolyzed with mutanolysin (M-1 enzyme) [2].
• Metschnikowia drosophilae was found in morning glory (Ipomoea sp.) flowers and associated Drosophila bromeliae on Grand Cayman Island. Its nutritional profile is atypical of the genus, being the only species that does not utilize sucrose or maltose as carbon sources, and one of the few that does not utilize melezitose [3].
• The AGT1 permease is a alpha-glucoside-H+ symporter responsible for the active transport of maltose, trehalose, maltotriose, alpha-methylglucoside, melezitose and sucrose [4].
• Hemoglobin release by the cytolysin was completely inhibited by the presence of raffinose or melezitose, but K+ release was not affected [5].
• Presence of melezitose and stachyose indicated that black flies had fed on homopteran honeydew [6].

Biological context of Melezitose

• The results also indicate the presence of hydrolysis products of melezitose: (a) in flies previously starved and placed with Thelaxes infested oak, (b) in P.ariasi cryopreserved direct from the light traps hung in oak trees infested with Lachnus and Thelaxes, and (c) flies caught in a house [7].
• Both P3 and P4 showed high substrate specificity for sucrose, failing to use melezitose, raffinose, or stachyose as the substrates [8].
• 2. Concanavalin A hemagglutination can be specifically inhibited by the sugars mannose, glucose, arabohexulose, alpha-methyl-D-mannopyranoside, N-acetyl-D-glucosamine, maltose, sucrose, trehalose and melezitose [9].

Associations of Melezitose with other chemical compounds

• The hydrolysis of maltose, trehalose and melezitose confirmed the presence of alpha-glucosidase activity [10].
