Aromatic aminotransferases in coryneform bacteria.
Species of coryneform bacteria (Corynebacterium glutamicum, Brevibacterium flavum, and B. ammoniagenes) are capable of transaminating all three of the aromatic pathway intermediates; prephenate, phenylpyruvate, and 4-hydroxy-phenylpyruvate. Two molecular species of aromatic aminotransferase (denoted aminotransferase I and aminotransferase II) were partially purified from C. glutamicum and B. fl...
متن کاملImportance of Coryneform Bacteria in Infective Endocarditis
Coryneform bacteria have been defined as non-sporing Gram-positive rods with an irregular outline.1 Almost all can be grown aerobically and assigned to the class Actinobacteria which are characterized by a high guaninecytosine content (>50%) and specific 16S rDNA signature nucleotides.2 Some of the genera in this class are environmental bacteria but some (e.g., Actinomyces, Brevibacterium, Cory...
متن کاملBacterial glycobiology: rhamnose-containing cell wall polysaccharides in Gram-positive bacteria
The composition of the Gram-positive cell wall is typically described as containing peptidoglycan, proteins and essential secondary cell wall structures called teichoic acids, which comprise approximately half of the cell wall mass. The cell walls of many species within the genera Streptococcus, Enterococcus and Lactococcus contain large amounts of the sugar rhamnose, which is incorporated in c...
متن کاملO-Acetylation of Plant Cell Wall Polysaccharides
Plant cell walls are composed of structurally diverse polymers, many of which are O-acetylated. How plants O-acetylate wall polymers and what its function is remained elusive until recently, when two protein families were identified in the model plant Arabidopsis that are involved in the O-acetylation of wall polysaccharides - the reduced wall acetylation (RWA) and the trichome birefringence-li...
متن کاملMicroanalysis of plant cell wall polysaccharides.
Oligosaccharide Mass Profiling (OLIMP) allows a fast and sensitive assessment of cell wall polymer structure when coupled with Matrix Assisted Laser Desorption Ionisation Time Of Flight Mass Spectrometry (MALDI-TOF MS). The short time required for sample preparation and analysis makes possible the study of a wide range of plant organs, revealing a high degree of heterogeneity in the substitutio...
