Specificity of phenylalanine uptake in cells grown in MA mediuma.
| |||||||||||||||||||||||||||||||||||
High-affinity phenylalanine uptake was measured at 4 min with L-[14C]-phenylalanine 20 M and the unlabelled amino acids were added at 200 M. Control values in the absence of competitor in strains Y294, Y294bap2, and Y294agp1 were 2.29, 0.32, and 1.91 mol g−1, respectively. DL-trifluoroleucine. -2-thienylalanine. |
