| Abstract: | In an attempt to isolate a plant malonyl-coenzyme A:acyl carrier protein transacylase cDNA clone, by direct genetic selection in an Escherichia coli fabD mutant (LA2-89) with a maize cDNA expression library, a Zea mays cDNA clone encoding a GTP-binding protein of the ARF family was isolated. Complementation of a mutation affecting bacterial membrane lipid biosynthesis by a plant ARF protein, could indicate the existence of as yet unidentified bacterial equivalents of this ubiquitous eucaryotic GTP-binding protein. |
