abstract = {Alanine : glyoxylate aminotransferase is one of three
different enzymes used for glycine synthesis in
Saccharomyces cerevisiae. The open reading frame YFL030w
(named AGX1 in the following), encoding this enzyme, was
identified by comparing enzyme specific activities in
knockout strains. While $100\%$ activity was detectable in
the parental strain, $2\%$ was found in a YFL030w::kanMX4
strain. The ORF found at that locus was suspected to encode
alanine : glyoxylate aminotransferase because its predicted
amino acid sequence showed $23\%$ identity to the human
homologue. Since the YFL030w::kanMX4 strain showed no
glycine auxtrophic phenotype, AGX1 was replaced by KanMX4 in
a Delta GLY1 Delta SHM1 Delta SHM2 background. These
background mutations, which cause inactivation of threonine
aldolase, mitochondrial and cytosolic serine
hydroxymethyltransferase, respectively, lead to a
conditional glycine auxotrophy. This means that growth is
not possible on glucose but on ethanol as the sole carbon
source. Additional disruption of AGX1 revealed a complete
glycine auxotrophy. Complementation was observed by
transformation with a plasmid-encoded AGX1.},
