From: Construction of efficient xylose utilizing Pichia pastoris for industrial enzyme production
Xylose utilizing pathway in engineered Pichia pastoris . XR, putative xylose reductase (encoded by PAS_chr3_0744); XDH, putative xylitol dehydrogenase (encoded by PAS_chr1-1_0490); XI, xylose isomerase (derived from Orpinomyces spp.); XK, putative xylulokinase (encoded by PAS_chr1-1_0280). PPP, pentose phosphate pathway. The XR and XDH consist of the putative oxidoreductase xylose pathway of P. pastoris. The XI xylose pathway is heterologously introduced by over-expression of Orpinomyces spp. XI gene in P. pastoris.
