Functional characterization of the Arabidopsis thaliana nitrate transporter CHL1 in the yeast Hansenula polymorpha.

Plant molecular biology - 1 Oct 2008

Martín Yusé, Navarro Francisco J, Siverio José M

Abstract excerpt

CHL1 (AtNRT1.1) is a dual-affinity nitrate transporter of Arabidopsis thaliana, in which phosphorylation at Thr 101 switches CHL1 from low to high nitrate affinity. CHL1 expressed in a Hansenula polymorpha high-affinity nitrate-transporter deficient mutant (Deltaynt1) restores nitrate uptake and growth. These events take place at nitrate concentrations as low as 500 microM, suggesting that CHL1 has a...
