Characterization of Vitamin K₉(H) from Mycobacterium phlei

The Menaquinone System in the Classification of Coryneform and Nocardioform Bacteria and Related Organisms

“…The menaquinone-8 with dehydrogenated isoprene units of the C. diphtheriae was in agreement with that reported by SCHOLES and KING (16) and BEAU et al (14). The MK-9 (H2) obtained here in M. phlei and M. tuberculosis coincided with that described by GALE et al (17) and BEAU et al (14). A unique MK system with tetrahydrogenated isoprene units was found in A. simplex and B, lipolyticum.…”

The Menaquinone System in the Classification of the Genus Nocardia

“…It is notable that N. minima, a member of the morphological group ii, possessed the MK-8(H4) system as in most species of the first group of morphology, but this system of menaquinone is considered to be reasonable as will be discussed below. Another exception was N. rubropertincta exhibiting a longer isoprenolog composed of MK-9(H2), this quinone being distributed in a number of other species in corynebacteria and mycobacteria such as C. xerosis, C. glutamicum, M. tuberculosis, and M. phlei (5,13,14).…”

Menaquinone as Well as Ubiquinone as a Crucial Component in the Escherichia coli Respiratory Chain

“…Archaea contains mainly MKs, which are often dehydrogenated. The major MK in Mycobacterium phlei is MK-9(H 2 ) (Gale et al, 1963), whereas the major MK in Corynebacterium diphtheriae is MK-8(H 2 ) (Scholes & King, 1965). Such dihydromenaquinones are widespread in corynebacteria and mycobacteria, whereas even more highly saturated MKs occur in certain actinomycetes (Collins et al, 1977;Lancaster, 2003).…”
