E. Shrago et al., FATTY ACYL COA ESTERS AS REGULATORS OF CELL-METABOLISM, Prostaglandins, leukotrienes and essential fatty acids, 52(2-3), 1995, pp. 163-166
Long chain fatty acyl CoA esters have the ability to interact with cer
tain proteins and thereby serve as effecters in cell metabolism, In pa
rticular, they can displace nucleotides from specific nucleotide depen
dent or binding proteins and interfere with their action. The ADP/ATP
carrier and uncoupling protein are two examples where the interplay of
nucleotide and acyl CoA binding to the proteins regulate their functi
on. Other proteins such as glucokinase can be considered in this group
, In certain tissues like liver they are affected during fasting and i
nsulin deficiency, and when serum fatty acids and liver acyl CoA level
s are elevated, More recently, an acyl CoA binding protein in E. coli
has been found to be a transcription factor for gene regulation of fat
ty acid metabolism enzymes. There appears to be some consensus:in the
amino acid sequence for acyl CoA binding sites on these proteins which
serve a variety of important roles in cellular metabolism.
