Metalloproteins — proteins containing metal atoms or clusters — are involved in a wide range of important biological processes. Recent advances in our understanding of metalloproteins include how enzymes containing complex metal clusters metabolize small gaseous molecules, how proteins containing iron–sulphur
Copper and iron metalloproteins are the primary oxidases, oxygenases and oxygen carriers in all animal cells. This has been attributed to the intrinsic favorable chemi- cal properties of these two metal ions, their availability in sea water, their role in the adaptation to the aerobic environment, and the subsequent
This chapter covers the most relevant aspects of sample preparation and analysis method for identification and quantification of metalloproteins in their native forms. It focuses on the preservation of the metal-protein complex. If the metalloprotein analysis does not aim to detect intact metal complexes present in a biological
Metalloproteins are an immensely diverse class of biological coordination com- pounds. The most important biochemical processes, including respiration, oxygenic photosynthesis, regulation of transcription and translation, nitrogen fixation, and metabolism of xenobiotics, depend on metalloproteins. Metalloenzymes were

Recently, the crystal structure of its reconstituted holoenzyme was solved and revealed the
Metalloprotein and redox protein design are rapidly advancing toward the chemical synthesis of novel proteins that have predictable structures and functions. Current data demonstrate a breadth of successful approaches to metallopeptide and metalloprotein design based on de novo, rational and combinatorial strategies.
4 May 2016 Abstract: Metal ions play a functional role in numerous biochemical processes and cellular pathways. Indeed, about 40% of all enzymes of known 3D structure require a metal ion to be able to perform catalysis. The interactions of the metals with the macromolecular framework determine their chemical.
Metalloproteins with one labile coordination site around the metal centre are known as metalloenzyme. As with all enzymes, the shape of the active site is crucial. The metal ion is usually located in a pocket whose shape fits the substrate. The metal ion catalyzes reactions which are hard to achieve in organic chemistry.
20 Dec 2017 Full-text (PDF) | Almost half of all enzymes must associate with a particular metal to function. An ambition is to understand why each metal-protein partnership arose and how it is maintained. Metal availability provides part of the explanation, and has changed over geological time and varies betw
