| Highly efficient incorporation of exogenously supplied amino acids by these three auxotroph strains has been demonstrated using recombinant galactose oxidase. |
| To retain the AaargB sequence in the arginine auxotroph, the AaargB function was disrupted by insertion mutagenesis. |
| This plasmid was first transformed into glycine auxotroph of E. coli strain and subsequently transformed into lysine auxotroph of Mycobacterium bovis BCG strain to generate vaccine BCG. HIVA2auxo. |
| The yeast morphotype but not the mold, for example, has a cysteine dioxygenase activity and is a cysteine auxotroph. |
| This drastic increase in gene-targeting frequency reduced the labor required to isolate auxotrophic mutants, such as an arginine auxotroph, without the use of counter-selective compounds. |
| Differential expression of Met auxotroph, Escherichia coli DL41 pCOCK, has revealed proteomic variation in cells forced to use TeMet in the translation of proteins. |
