In silico and in vitro exploration of a tyrosinase for biocatalytic production of catechols

open access: yesFEBS Open Bio, EarlyView.
Tyrosinase from Ralstonia pseudosolanacearum is a promising biocatalyst for producing valuable catechols from monophenol substrates. This tyrosinase is uniquely suited to this due to its high monophenolase : diphenolase ratio. We combined in silico docking and in vivo kinetic characterisation of this tyrosinase with 11 industrially relevant monophenols,

Polyphenol contents and DPPH-radical scavenging activities of Teas from Hasu (Nelumbo nucifera Gaertn.) [PDF]

open access: yes, 2005
P(論文)蓮を用いた茶についてのポリフェノール含量や抗酸化能についての報告例がないので、それらについて調べた。1.蓮芯茶のポリフェノール量は少なかったが、蓮花茶と蓮茶のそれは静岡煎茶のそれよりも多かった。2.DPPHラジカル消去能は、蓮花茶と蓮茶が高く、ポリフェノール含量との問に正の相関があった。3.総カテキン量は、蓮花茶や蓮茶よりウーロン茶や静岡煎茶の方が多かった。4.蓮花茶や蓮茶には、DPPHラジカル消去能に寄与するカテキン類以外の成分の関与が推察され、その1つにクロロゲン酸類の存在が指摘された ...
