  2. Iron–sulfur protein - Wikipedia

    en.wikipedia.org/wiki/Iron–sulfur_protein

    Iron–sulfur proteins are proteins characterized by the presence of iron–sulfur clusters containing sulfide-linked di-, tri-, and tetrairon centers in variable oxidation states. Iron–sulfur clusters are found in a variety of metalloproteins , such as the ferredoxins , as well as NADH dehydrogenase , hydrogenases , coenzyme Q – cytochrome ...

  3. Succinylation - Wikipedia

    en.wikipedia.org/wiki/Succinylation

    In biochemistry, succinylation is a posttranslational modification where a succinyl group (−CO−CH 2 −CH 2 −CO 2 H) is added to a lysine residue of a protein molecule. This modification is found in many proteins, including histones. [1]

    en.wikipedia.org/wiki/Iron–sulfur_cluster

    Iron–sulfur clusters are molecular ensembles of iron and sulfide. They are most often discussed in the context of the biological role for iron–sulfur proteins , which are pervasive. [ 2 ] Many Fe–S clusters are known in the area of organometallic chemistry and as precursors to synthetic analogues of the biological clusters.

    Iron is also stored as a pigment called hemosiderin, which is an ill-defined deposit of protein and iron, created by macrophages where excess iron is present, either locally or systemically, e.g., among people with iron overload due to frequent blood cell destruction and the necessary transfusions their condition calls for. If systemic iron ...

  7. Iron–sulfur cluster biosynthesis - Wikipedia

    en.wikipedia.org/wiki/Iron–sulfur_cluster...

    The iron sulfur proteins contain iron–sulfur clusters, some with elaborate structures, that feature iron and sulfide centers. One broad biosynthetic task is producing sulfide (S 2-), which requires various families of enzymes. Another broad task is affixing the sulfide to iron, which is achieved on scaffolds, which are nonfunctional.
