ID 3.1.3.111 DE decaprenylphosphoryl-5-phosphoribose phosphatase. CA trans,octa-cis-decaprenylphospho-beta-D-ribofuranose 5-phosphate + H2O = CA trans,octa-cis-decaprenylphospho-beta-D-ribofuranose + phosphate. CC -!- The enzyme, studied from mycobacteria, in involved in the CC biosynthesis of trans,octacis-decaprenylphospho-beta-D- CC arabinofuranose, which serves in those organisms as the CC arabinofuranose donor for the biosynthesis of the cell wall polymers CC arabinogalactan and lipoarabinomannan.
