The main component of the metabolic by-products of fermentation by Propionibacterium freudenreichii ET-3 is 1,4-dihydroxy-2-naphthoic acid (DHNA), which has a naphthoquinone skeleton, as in vitamin K2. This study showed that DHNA improved bone mass reduction with osteoporosis model mice caused

Propionibacterium freudenreichii ET-3 (7025) culture, a cell-free product of whey fermentation by P. freudenreichii ET-3, has been shown to promote the growth of Bifidobacteria through the action of 1,4-dihydroxy-2-naphthoic acid (DHNA). Here we report the results of two clinical studies

In this study, we investigated the role of menaquinone biosynthesis genes in selenate reduction by Enterobacter cloacae SLD1a-1 and Escherichia coli K12. A mini-Tn5 transposon mutant of E. cloacae SLD1a-1, designated as 4E6, was isolated that had lost the ability

Four independent menaquinone (vitamin K(2))-deficient mutants of Escherichia coli, blocked in the conversion of o-succinylbenzoate (OSB) to 1,4-dihydroxy-2-naphthoate (DHNA), were found to represent two distinct classes. Enzymatic complementation was observed when a cell-free extract of one mutant was mixed with

1,4-Dihydroxy-2-naphthoate:polyprenyltransferase was detected in the membrane fraction from Micrococcus luteus. The specificity of the enzyme ws so tolerant as regards the prenyl-donating substrate that prenyl pyrophosphates ranging in chain length from C15 to C45 were active as substrates. The monophosphate
