Abstract/OtherAbstract:
Dolichyl phosphates of various chain length ranging from 7 to 22 isoprene units were tested as lipid acceptors in transglycosylation reactions in chicken liver and Hepatoma MC-29. In the presence of exogenous dolichyl phosphate mixture (18 and 19 isoprene units) the synthesis of dolichyl pyrophosphate N-acetylglucosamine and dolichyl phosphate mannose increased 3 times both in the liver and Hepatoma MC-29, while the formation of dolichyl phosphate glucose was 4 fold higher in the liver and 6-fold higher in Hepatoma MC-29. In liver microsomes the maximum rate of the stimulation of glycosylation was achieved by exogenous dolichyl phosphates, containing 18 and 19 isoprene units, while glycosyl transferases in microsomes from Hepatoma MC-29 did not show any structural requirements to the chain length of dolichyl phosphates.
