Protein Variants

Protein Variants Comment Organism
G68S the mutant called lignescens, a temperature-sensitive mutant that exhibits ectopic lignin deposition and growth defects under high-temperature conditions, is due to single base transition G68S in glucosamine-6-phosphate N-acetyltransferase. When exposed to the restrictive temperature, the mutant strain contains a significantly smaller amount of UDP-GlcNAc than the wild type. The growth defects and ectopic lignification of the mutant are suppressed by the addition of UDP-GlcNAc. N-glycans are reduced and luminal binding protein 3, a typical UPR gene, is expressed in the mutant strain at the restrictive temperature. Treatment with UPR-inducing reagents phenocopies the mutant Arabidopsis thaliana
