4-(2'-Carboxyphenyl)-4-oxobutyryl coenzyme A ester, an intermediate in vitamin K2 (menaquinone) biosynthesis.
Kolkmann R., Leistner E.
Enzyme preparations from Mycobacterium phlei, Escherichia coli and Galium mollugo cell suspension cultures were incubated in the presence of 4-(2'-carboxyphenyl)-4-oxobutyrate (i.e. o-succinylbenzoic acid, OSB, 1), ATP, coenzyme A and Mg2+.

Enzyme preparations from Mycobacterium phlei, Escherichia coli and Galium mollugo cell suspension cultures were incubated in the presence of 4-(2'-carboxyphenyl)-4-oxobutyrate (i.e. o-succinylbenzoic acid, OSB, 1), ATP, coenzyme A and Mg2+. The main product isolated from the incubation mixture was 4-(2'-carboxyphenyl)-4-oxobutyryl coenzyme A ester (2) as determined by comparison with synthetic coenzyme A esters. Synthetic and enzymically formed 4-(2'-carboxyphenyl)-4-oxobutyryl coenzyme A ester (2) was shown to be enzymically converted to an intermediate in vitamin K2 biosynthesis viz. 1,4-dihydroxy-2-naphthoic acid (5). The enzymic formation of 2-(3'-Carboxypropionyl)benzoyl coenzyme A ester (3) and 4-(2'-carboxyphenyl)-4-oxobutyryl-di-coenzyme A ester (4) was also observed. They appeared in minor amounts, however. These esters were not convertible to 1,4-dihydroxy-2-naphthoic acid (5). << Less

Menaquinone (vitamin K2) biosynthesis: conversion of o-succinylbenzoic acid to 1,4-dihydroxy-2-naphthoic acid by Mycobacterium phlei enzymes.
Meganathan R., Bentley R.
The coenzyme A (CoA) and adenosine 5'-triphosphate-dependent conversion of o-succinylbenzoic acid (4-[2'-carboxyphenyl]-4-oxobutyric acid) to 1,4-dihydroxy-2-naphthoic acids is an important step in menaquinone (vitamin K2) biosynthesis.

The coenzyme A (CoA) and adenosine 5'-triphosphate-dependent conversion of o-succinylbenzoic acid (4-[2'-carboxyphenyl]-4-oxobutyric acid) to 1,4-dihydroxy-2-naphthoic acids is an important step in menaquinone (vitamin K2) biosynthesis. Cell-free extracts catalyzing this conversion, obtained from Mycobacterium phlei, were separated into three protein fractions by treatment with protamine sulfate. The second fraction (fraction B) and the supernatant (fraction S) alone did not catalyze dihydroxynaphthoate formation, but did so in combination. All of the results were consistent with the formation of an unstable intermediate, likely an o-succinylbenzoyl-CoA compound, by the action of fraction S. Adenosine 5'-triphosphate was required in this reaction and adenosine 5'-monophosphate was formed. This enzyme activity was termed o-succinylbenzoyl-CoA synthetase: the enzyme showed a marked stability to 0.1 N hydrochloric acid. The presumed o-succinylbenzoyl-CoA derivate was rather unstable; under a variety of conditions, it was converted to a spirodilactone form of o-succinylbenzoate. Fraction B contained an enzyme, termed naphthoate synthase, which converted the o-succinylbenzoyl-CoA derivative to 1,4-dihydroxy-2-naphthoate. << Less

Enzymatic synthesis, characterization, and metabolism of the coenzyme A ester of o-succinylbenzoic acid, an intermediate in menaquinone (vitamin K2) biosynthesis.

The enzymatic synthesis of the "active" o-succinylbenzoic acid is described and the factors controlling its formation are investigated.

The enzymatic synthesis of the "active" o-succinylbenzoic acid is described and the factors controlling its formation are investigated. Tritium-labeled coenzyme A is incorporated into "active" o-succinylbenzoic acid, but label from [2-3H]ATP or [gamma-32P is not, indicating that the active compound is a coenzyme A thio ester(2). The compound is shown by two different methods to contain 1 mol only of coenzyme A per mol of o-succinylbenzoic acid. The o-succinylbenzoic and coenzyme A ester (2) is unstable at alkaline and neutral pH, but is fairly stable under acid conditions. The coenzyme A ester (2) is converted to 1,4-dihydroxy-2-naphthoic acid (3) by enzyme preparations from Mycobacterium phlei and Escherichia coli without any cofactor requirement. << Less
