Cloned(Commentary)

EC Number Cloned (Comment) Organism
3.1.3.36 full-length 5PTase13-encoding sequence is N-terminally fused to a polyhistidinetag and a T7-tag and expressed in Escherichia coli cells Arabidopsis thaliana

Protein Variants

EC Number Protein Variants Comment Organism
3.1.3.36 additional information disruption of the gene 5PTase13 results in shortened hypocotyls and expanded cotyledons. Suppression of 5PTase13 expression rescues the elongated hypocotyls in the phototropin1 or phototropin1 phototropin2 mutants. Further analysis shows that the blue light-induced elevation of cytosolic Ca2+ is inhibited in the phot1 mutant but enhanced in the 5pt13 mutant, suggesting that 5PTase13 antagonizes phototropin1-mediated effects on calcium signaling under blue light Arabidopsis thaliana
