9132063-1	1997	The Arabidopsis G alpha subunit, GP alpha1, was expressed within Escherichia coli by co-transformation with the expression vector and the dnaY gene which encodes tRNA(Arg)(AGA/AGG) Isolation of the recombinant GP alpha1 in a highly pure form could be achieved by a combination of anion exchange and dye affinity chromatography or by a single step affinity procedure via chromatography on 4-amino-anilido-GTP agarose.	4-amino-anilido-gtp	388-407	G protein alpha subunit 1	Arabidopsis thaliana	4-42
