Galactose-1-phosphate uridylyltransferase (GALT) catalyzes the reversible conversion of glucose-1-phosphate and UDP-galactose to galactose-1-phosphate and UDP-glucose. This enzyme is also responsible for one of the biochemical steps that produce the precursors of agar and agarose. In this study, we report the molecular cloning and sequence analyses of a(More)
GDP-mannose-3′,5′-epimerase (GME) is an enzyme involved in the biosynthesis of GDP-l-galactose which is a building unit of agar and cell wall polysaccharides. GME catalyzes the formation of GDP-β-l-galactose and GDP-l-gulose from GDP-mannose. In this study, the gene and transcript encoding GME from the red alga Gracilaria changii (GcGME) were cloned.

Many bacterial epiphytes of agar-producing seaweeds secrete agarase that degrade algal cell wall matrix into oligoagars which elicit defense-related responses in the hosts. The molecular defense responses of red seaweeds are largely unknown. In this study, we surveyed the defense-related transcripts of an agarophyte, Gracilaria changii, treated with(More)
