Pasteurellaceae

The family of Pasteurellaceae (y-proteobacteria) comprises genera Haemophilius, Histophilus and Pasteurella and Histophilus somnus. Structural studies of LPS from H. influenzae have identified a conserved core structure containing the...

NMPRT enzyme that converts Nm directly into NMN was originally characterized as a product of the nadV gene in Haemophilus ducreyi This organism, as most other members of Pasteurellaceae, lacks the machinery for amidation of the pyridine carboxylate (as well as most other enzymes of NAD synthesis, see Section... 

H. ducreyi and several other V-factor-independent members of the Pasteurellaceae group H. somnus, Actinobacillus pleuropneumoniae, and Actinomycetemcomitans) harbor the NMNAT enzyme (NadV) that allows them to grow in the presence of Nm (but not Na) in the medium (Section 7.08.2.2). 

Three important natural succinate producers, Actinobacillus succinogenes, Mannheimia succiniciproducens, and Basfia succiniciproducens, all members of the Pasteurellaceae family within the y-proteobacteria, were isolated from mmen contents (Guettler et al., 1999 Lee et al., 2002 Kuhnert et al., 2010). All three species are capnophilic (thrive in the presence of high concentrations of carbon dioxide), facultative anaerobic bacteria which share a similar fermentative metabolism resulting in the production of succinate as major product accompanied by pyruvate dissimilation to lactate, acetate, formate, and in some cases to ethanol as minor products. 

In summary, all three members of the Pasteurellaceae family described above,...

A. succinogenes, a bacterium from the family Pasteurellaceae, was isolated from the rumen of a cow at Michigan State University (Guettler et al., 1996,1999). The bacterium is a gramnegative, capnophilic, facultative anaerobe.
