Genomic fragment containing the Tps1 transcription unit. A stop codon has been introduced before the trehalose-6-phosphate phosphatase (TPP) domain, resulting in a protein consisting of only the trehalose-6-phosphate synthase (TPS) domain.
Tps1TPS fails to rescue Tps1d2
Expression of Tps1TPS fails to rescue the lethality and the decreased circulating glucose and trehalose levels observed in Tps1d2/Tps1d2 mutants.
