Metabolic engineering of Lactobacillus plantarum for production of L-ribulose.
L-Ribulose is a rare and expensive sugar that can be used as a precursor for the production of other rare sugars of high market value such as L-ribose. In this work we describe a production process for L-ribulose using L-arabinose, a common component of polymers of lignocellulosic materials, as the starting material. A ribulokinase-deficient mutant of the heterofermentative lactic acid bacteriu...
متن کاملAn expedient synthesis of L-ribulose and derivatives.
A significant improvement in the production of l-ribulose from inexpensive and commercially available starting materials, L-arabinose and sodium aluminate, is demonstrated. This has facilitated expeditious access to gram-scale quantities of L-ribulofuranoside derivatives.
متن کاملImmobilization of Bacillus licheniformis L-arabinose isomerase for semi-continuous L-ribulose production.
Bacillus licheniformis L-arabinose isomerase (BLAI) with a broad pH range, high substrate specificity, and high catalytic efficiency for L-arabinose was immobilized on various supports. Eupergit C, activated-carboxymethylcellulose, CNBr-activated agarose, chitosan, and alginate were tested as supports, and Eupergit C was selected as the most effective. After determination of the optimum enzyme ...

متن کاملOxygen inhibition and other properties of soybean ribulose 1,5-diphosphate carboxylase.
n-Ribulose-l , 5-di-P carboxylase, purified from soybeans, had K, values of 0.13 XnM for COS and 0.19 mM for ribulose1,5-di-P under a Nz atmosphere. O2 inhibited 14C02 incorporation by the enzyme and this inhibition was rapidly reversed by Ns. Inhibition was competitive with respect to CO2 and uncompetitive with respect to ribulose-1,5-di-P. The Ki for O2 was 0.8 mM. This O2 inhibition, togethe...
