Wound induced changes in phenolic metabolism and tissue browning are altered by heat shock
Wounding is one of many abiotic stresses that produce signals that propagate from injured into adjacent non-injured tissues and induce the de novo synthesis of specific wound-induced proteins. Some of these induced proteins are enzymes of phenolic metabolism, such as phenylalanine ammonia-lyase (PAL), whose increased activity leads to the accumulation of phenolic compounds (e.g., chlorogenic ac...
متن کاملAltered sensitivity of carnitine palmitoyltransferase to inhibition by malonyl-CoA in ketotic diabetic rats.
Carnitine palmitoyltransferase of liver mitochondria prepared from ketotic diabetic rats has a diminished sensitivity to inhibition by malonyl-CoA compared with carnitine palmitoyltransferase of mitochondria prepared from normal fed rats.
متن کاملCarnitine palmitoyltransferase in cardiac ischemia. A potential site for altered fatty acid metabolism.
The sensitivity of carnitine palmitoyl coenzyme A (CoA) transferase I to inhibition of its activity by malonyl-CoA is progressively reduced in mitochondria isolated from ischemic cardiac cells as blood flow decreases to 30% or less of the preocclusion flow. The activity of carnitine palmitoyl-CoA transferase I in mitochondria isolated from nonischemic cardiac cells demonstrates incomplete inhib...
متن کاملMalonyl-CoA metabolism in cardiac myocytes.
(1) Malonyl-CoA is thought to play a signalling role in fuel-selection in cardiac muscle, but the rate at which the concentration of this potential signal can be changed has not previously been investigated. (2) Rapid changes in cellular malonyl-CoA could be observed when rat cardiac myocytes were incubated in glucose-free medium followed by re-addition of 5 mM glucose, or when cells were trans...
متن کاملProduction of L-carnitine by secondary metabolism of bacteria
The increasing commercial demand for L-carnitine has led to a multiplication of efforts to improve its production with bacteria. The use of different cell environments, such as growing, resting, permeabilized, dried, osmotically stressed, freely suspended and immobilized cells, to maintain enzymes sufficiently active for L-carnitine production is discussed in the text. The different cell states...
