The active site of magnesium chelatase [PDF]
The insertion of magnesium into protoporphyrin initiates the biosynthesis of chlorophyll, the pigment that underpins photosynthesis. This reaction, catalysed by the magnesium chelatase complex, couples ATP hydrolysis by a ChlID motor complex to chelation within the ChlH subunit. We probed the structure and catalytic function of ChlH using a combination

Cloning and Phylogenetic Relationships Analysis of an Oxidoreductase Gene in Product Pathway of Ethylene Hormone [PDF]
1-aminocyclopropane-1-carboxylic acid oxidase (ACO) enzyme is a member of the Fe (II-dependent family of oxidases/ oxygenases) and for activity requires Fe2+ as cofactors and ascorbate as a co-substrate.

We present here a thermodynamic assessment of the stability behavior in acid environment at 298 and 353 K (80°C) of two iron (II) hexa‐aza‐macrocyclic complexes and of an hexa‐aza‐iron‐based site (FeIIN(4+2)/C) that should potentially be active for the ...

The Active-site Environment of Rhodopsin [PDF]
The 11-cis-retinal binding site of rhodopsin is of great interest because it is buried in the membrane but yet must provide an environment for charged amino acids. In addition, the active-site lysine residue must be able to engage in rapid Schiff base formation with 11-cis-retinal at neutral and lower pH values.

Structural and biophysical aspects of l-asparaginases: a growing family with amazing diversity
l-Asparaginases have remained an intriguing research topic since their discovery ∼120 years ago, especially after their introduction in the 1960s as very efficient antileukemic drugs.

Copper Active Sites in Biology [PDF]
Based on its generally accessible I/II redox couple and bioavailability, copper plays a wide variety of roles in nature that mostly involve electron transfer (ET), O2 binding, activation and reduction, NO2− and N2O reduction and substrate activation.
