アプリケーション
D-Ribulose-5-phosphate 3-Epimerase is an enzyme that converts the reversible conversion of D-ribulose 5-phosphate into D-xylulose 5-phosphate, which is important for the cellular response against oxidative stress [1]. D-Ribulose-5-phosphate 3-Epimerase is involved in the pentose phosphate pathway, pentose and glucuronate interconversions and carbon fixation. Product R3251 is from baker′s yeast and is provided as a lyophilized powder. It is useful in enzyme systems requiring low sulfate.
生物化学的／生理学的作用
RPE is a metalloenzyme and has been shown to use the divalent Zn2+ ion predominantly for catalysis. Human D-ribulose-5-phosphate 3-epimerase (hRPE) has been shown to use Fe2+ for catalysis [1].

A cDNA clone encoding the chloroplast enzyme pentose-5-phosphate 3-epimerase (EC 5.1.3.1) in potato (Solanum tuberosum) was isolated and sequenced. The deduced sequence of 235 amino acids is similar to protein sequences of bacterial epimerases. Northern blot analysis showed the highest

Lateral gene transfer is increasingly invoked to explain phylogenetic results that conflict with our understanding of organismal relationships. In eukaryotes, the most common observation interpreted in this way is the appearance of a bacterial gene (one that is not clearly

Enzymes that share the (beta/alpha) 8-barrel fold catalyze a diverse range of reactions. Many utilize phosphorylated substrates and share a conserved C-terminal (beta/alpha) 2-quarter barrel subdomain that provides a binding motif for the dianionic phosphate group. We recently reported functional

Suppression subtractive hybridisation was used to isolate genes differentially regulated by low levels (UV-B(BE,300) 0.13 W m(-2)) of ultraviolet-B radiation (UV-B; 290-320 nm) in Pisum sativum. Six genes were regulated, two of which were novel. The mRNA levels for these
