2.3.3.17 A290G the strain harbouring the MAM1 variant produces more thrice-elongated methionine than the native MAM1 756230 2.3.3.17 A290S unchanged composition of chain-elongated amino acids. The strain harbouring the MAM1 variant produces more thrice-elongated methionine than the native MAM1 756230 2.3.3.17 A290T in the strain harbouring the MAM1 variant, SSU3 protein level is higher than in the strain harbouring wild-type MAM1. No chain-elongated amino acid products are found 756230 2.3.3.17 A290T the strain harbouring the MAM1 variant does not produce any of the chain-elongated amino acid products 756230 2.3.3.17 G259A in the strain harbouring the MAM1 variant, SSU3 protein level is higher than in the strain harbouring wild-type MAM1. No chain-elongated amino acid products are found 756230 2.3.3.17 G259A the strain harbouring the MAM1 variant does not produce amino acids elongated more than twice 756230 2.3.3.17 G259A the strain harbouring the MAM1 variant does not produce any of the chain-elongated amino acid products 756230 2.3.3.17 T257C the strain harbouring the MAM1 variant produces more thrice-elongated methionine than the native MAM1 756230 2.3.3.17 T257D in the strain harbouring the MAM1 variant, SSU3 protein level is higher than in the strain harbouring wild-type MAM1. The strain harbouring the MAM1 variant produces more thrice-elongated methionine than the native MAM1 756230 2.3.3.17 T257G the strain harbouring the MAM1 variant does not produce amino acids elongated more than twice 756230 2.3.3.17 T257G/G259A the strain harbouring the MAM1 variant produces tetra-elongated methionine 756230 2.3.3.17 T257G/G259A/A290G the strain harbouring the MAM1 variant produces tetra-elongated methionine. Unchanged composition of chain-elongated amino acids, although the production is dramatically reduced 756230 2.3.3.17 T257G/G259A/L186M the strain harbouring the MAM1 variant produces tetra-elongated methionine 756230 2.3.3.17 T257N T257S shows nearly 3fold higher L-homophenylalanine production than the native MAM1. In the strain harbouring the MAM1 variant, SSU3 protein level is higher than in the strain harbouring wild-type MAM1. Low levels of chain-elongated amino acid products are found 756230 2.3.3.17 T257S the strain harbouring the MAM1 variant shows higher MAM1 levels, although this does not result in correspondingly higher levels of chain-elongated products 756230
