1 Recombinant Arabidopsis SQD1 converts udp-glucose and sulfite to the sulfolipid head group precursor UDP-sulfoquinovose in vitro. Sulfites sulfoquinovosyldiacylglycerol 1 Arabidopsis thaliana
2 Among different possible sulfur donors tested, sulfite led to the formation of UDP-sulfoquinovose in the presence of UDP-glucose and SQD1. Sulfites sulfoquinovosyldiacylglycerol 1 Arabidopsis thaliana
3 Approximate K(m) values of 150 microm for UDP-glucose and 10 microm for sulfite were established for SQD1. Sulfites sulfoquinovosyldiacylglycerol 1 Arabidopsis thaliana
4 Based on our results, we propose that SQD1 catalyzes the formation of UDP-sulfoquinovose from UDP-glucose and sulfite, derived from the sulfate reduction pathway in the chloroplast. Sulfites sulfoquinovosyldiacylglycerol 1 Arabidopsis thaliana
