The kinetic properties of carnitine acetyltransferase from the skeletal muscle of the Arabian camel (Camelus dromedarius) were studied. The enzyme showed an optimum pH between 7.2 and 8.2. Reciprocal plots of data obtained by varying one substrate concentration while keeping

A photolabile reagent, p-azidophenacyl-DL-thiocarnitine, was synthesized and tested as a photoaffinity label for carnitine acetyltransferase (EC 2.3.1.7) from pigeon breast. p-Azidophenacyl-DL-thiocarnitine is an active-site-directed reagent for this acetyltransferase, since it is a competitive inhibitor (Ki 10 microM) versus carnitine. U.v.

The JAR human placental choriocarcinoma cells were found to transport carnitine into the intracellular space by a Na(+)-dependent process. The transport showed no requirement for anions. The Na+-dependent process was saturable and the apparent Michaelis-Menten constant for carnitine was 12.3

A large number of birth defects are related to nutrient deficiencies; concern that biotin deficiency is teratogenic in humans is reasonable. Surprisingly, studies indicate that increased urinary 3-hydroxyisovalerylcarnitine (3HIAc), a previously validated marker of biotin deficiency, is not a valid
