Ruthenium porphyrin-ß-cyclodextrin complexes as supramolecular enzyme models for regioselective cleavage of carotenoids [PDF]
, 2006 All naturally occurring vitamin A derives from enzymatic oxidative cleavage of β,β-carotene or other carotenoids with pro-vitamin A activity. Two metabolic pathways of β,β-carotene to retinal (vitamin A aldehyde) have been proposed: the central cleavage ...

Measurement of β-Glucobiose-Hydrolysis Activity and Comparison of Two β-Glucosidases [PDF]
, 1993 P(論文)β-グルコ2糖(G2)とグルコースオキシダーゼ(GOD)試薬を用いることによって、β-グルコシダーゼによるG2からのグルコース(G1)の遊離が測定された。アーモンドエムルシンのβ-グルコシダーゼはG2を加水分解してG1を生成し、転移物の生成は見られなかった。G1の遊離速度はラミナリビオース>ソホロース>セロビオース>ゲンチオビオースの順であった。本酵素はG2よりもp-ニトロフエニルβ-D-グルコシド(PNPG)に対し強い活性を有し、アリルβ-グルコシダーゼと分類されるのが妥当と思われる。一方 ...
