UDP-xylose and peroxide inhibited UGDH but not diaphorase staining activity in cultured monolayer FLS.

open access: yes, 2022
Cells were from a 23-year old male donor (passage 4). FLS stained for UGDH (A: bright field; B: phase contrast) or UGDH with UDP-xylose (C: bright field; D: phase contrast), diaphorase (E), or diaphorase with UDP-xylose (F).

UDP‐Apiose/UDP‐Xylose Synthase [PDF]

open access: yesEuropean Journal of Biochemistry, 1977
The UDP‐apiose/UDP‐xylose synthase from cell suspension cultures of parsley has been purified 1400‐fold by an improved method. The ratio of apiose to xylose formed from UDP‐D‐glucuronic acid (UDP‐GlcUA) remained constant throughout the purification procedure. Dodecylsulfate‐gel electrophoresis and sedimentation equilibrium measurements showed that this
