Alternative Pathway For Provision Of Acyl Coa Precursors For Fatty Acid Biosynthesis: Purification And Kinetic Characterization Of Phosphotransbutyrylase And Butyrate Kinase From Listeria Monocytogenes, Sirisha Sirobhushanam

Theses and Dissertations

Listeria monocytogenes is a foodborne pathogen that causes listeriosis, a disease characterized by gastroenteritis, meningitis, spontaneous miscarriages and high mortality rate among infected individuals. L. monocytogenes is a major concern in the food industry, due to its ability to grow at refrigeration temperatures and the zero tolerance policy of the FDA, resulting in expensive food recalls. Growth at low temperatures is aided in part by the high membrane content of branched-chain fatty acids (BCFAs) which imparts greater fluidity to the membrane. Mutants of L. monocytogenes impaired in BCFA biosynthesis display diminished growth at normal and low temperatures, exhibit lower tolerance …
