Abstract:
:Two sites for β-oxidation of fatty acids in pea (Pisum sativum L.) cotyledons exist. One site is the microbody, the other the mitochondrion. Mitochondrial β-oxidation of fatty acids is carnitine-dependent. The fatty acid permeates the membrane as palmitoylcarnitine which is formed from cytosolic-side palmitoyl-CoA by a carnitine palmitoyltransferase located on the exterior face of the inner mitochondrial membrane as a peripheral protein. A single-gated pore integral membrane translocator is proposed to exchange the palmitoylcarnitine for carnitine or acetylcarnitine across the membrane. An internal (matrix side) carnitine palmitoyltransferase then reforms palmitoyl-CoA which enters β-oxidation and subsequently the tricarboxylic-acid cycle.

PLANTA文献大全abstract:MAIN CONCLUSION:The HEUKCHEEM gene plays an important role in spine color formation. A white spine occurs due to two mutations in HEUKCHEEM and is closely related to the regional distribution of these mutants.
