The uptake of L-carnitine by Escherichia coli 044 K74 which is able to metabolize L-carnitine to gamma-butyrobetaine under anaerobic conditions was studied. The uptake system of E. coli was induced in the presence of L-carnitine or crotonobetaine. The optimum influx

The aim of this work was to understand the steps controlling the process of biotransformation of trimethylamonium compounds into L(-)-carnitine by Escherichia coli and the link between the central carbon or primary and the secondary metabolism expressed. Thus, the enzyme

Proteus sp. is able to catalyse the reversible transformation of crotonobetaine into L(-)-carnitine during aerobic growth. Contrary to other Enterobacteriaceae no reduction of crotonobetaine into gamma-butyrobetaine could be detected in the culture supernatants. Activities of L(-)-carnitine dehydratase, carnitine racemasing system

Enzymes involved in carnitine metabolism of Proteus sp. are encoded by the cai genes organised as the caiTABCDEF operon. The complete operon could be sequenced from the genomic DNA of Proteus sp. Amino acid sequence similarities and/or enzymatic analysis confirmed

The aim of this work was to understand the steps controlling the biotransformation of trimethylammonium compounds into L(-)-carnitine by Escherichia coli. The high-cell density reactor steady-state levels of carbon source (glycerol), biotransformation substrate (crotonobetaine), acetate (anaerobiosis product) and fumarate (as
