Phenylketonuria (PKU) is a metabolic disorder, in which loss of phenylalanine hydroxylase activity results in neurotoxic levels of phenylalanine. We used the Pah(enu2/enu2) PKU mouse model in short- and long-term studies of enzyme substitution therapy with PEGylated phenylalanine ammonia lyase (PEG-PAL conjugates) from 4 different species. The most therapeutically effective PAL (Av, Anabaena va...

In vitro fatty acid transfer to form complex lipids was observed in crude cell extracts of Anabaena variabilis using [1-(14)C]palmitoyl-acyl carrier protein, [1-(14)C]stearoyl-acyl carrier protein, and [1-(14)C]oleoyl-acyl carrier protein substrates. The data indicated that there was a rapid transfer of the fatty acids into the complex lipids. The greatest amount of radioactivity was observed i...

A particle-bound, Mg2+-dependent ATPase activity is investigated in cell-free extracts o f the cyanobacterium Anabaena variabilis. The enzyme can be clearly distinguished from the cyanobacterialcoupling factor o f photophosphoiylation and from the alkaline phosphatase. It requires low concentrations o f Ca2+ for maximal activity and is inhibited by orz/io-vanadate, indicating that the enzyme ma...
