Sebastien Dementin and colleagues now show that, while oxygen does interact with the active site- accepting an electron from the metals- it does not remain there.
The extent to which cannabidiol behaves as a competitive inhibitor of cytochrome P450depends on how tightly CBD binds to the active site of the metabolic enzyme before and after oxidation.
Most drug discovery approaches aimed at this target class have produced compounds that inhibit the active site of the enzymes through an irreversible modification.
To overcome the limit, a small part of the system is treated quantum-mechanically(typically active-site of an enzyme) and the remaining system is treated classically.
To overcome the limitation, a small part of the system is treated quantum-mechanically(typically active-site of an enzyme) and the remaining system is treated classically.
As the berry is currently thought to be the active part of the plant, this begs the question of whether the leaf of the plant should also be researched in more detail.”.
The actual binding site of the two water molecules is not known for certain, but in the PDB structure 1s5l a bicarbonate ion is bound to the cluster, providing a clue for location of the active site.
This process is controlled by one of three enzymes, named Ag85A, Ag85B, and Ag85C. Benjamin Davis, Clifton Barry and colleagues now show that, by studying the flexibility of the active site of these three enzymes, they can insert derivatives of trehalose containing fluorescent dyes into the M. tuberculosis cell wall.
From this, it became clear that charge distribution on the surface of the active sitesof RuBisCO is the deciding factor in the relative abundance of CO2 and oxygen near the active sites. CO2 concentrations are higher in RuBisCO with neutral charges on active site surfaces, so these types demonstrate superior CO2 recognition abilities.
この活性部位でアスピリンとイブプロフェンが作用します。
It's in this active site that aspirin and ibuprofen do their work.
この薬剤は、胃腸リパーゼのための可逆的活性部位阻害剤である。
This drug is a reversible active-site inhibitor for gastrointestinal lipases.
Zucは2量体を形成し、2量体界面に酵素活性部位を持つ。
Zuc forms a dimer, with an interface containing enzyme active sites.
酵素活性部位の溝の幅は狭いことから、2本鎖RNAは結合できないと考えられる。
The groove width in the enzyme active site is so small that it possibly excludes combinations with a double-stranded RNA.
この酵素は2つの同じサブユニットから構成されていて、それぞれが活性部位を持っている。
It is composed of two identical subunits, each with its own active site.
このように3種類の酵素はそれぞれ独立に進化して似た酵素活性部位を作ったことは明白である。
Thus it is apparent that these enzyme classes have evolved independently to create a similar enzyme active site.
このモデルでは、酵素の活性部位は特定の形状であり、基質のみがロックやキーのようにフィットします。
In this model, an enzyme's active site is a specific shape, and only the substrate will fit into it, like a lock and key.
Approaches the theoretical maximum; the enzyme active sites are almost all occupied and the reaction rate is determined by the intrinsic turnover rate of the enzyme.
