RUBREDOXINS Meaning and
Definition
-
Rubredoxins are a group of small, single-electron-transfer proteins that are widely present in bacteria, archaea, and some anaerobic eukaryotes. They belong to the family of iron-sulfur proteins and are characterized by their ability to bind a specific iron-sulfur cluster called the rubredoxin cluster.
Rubredoxins play a crucial role in electron transfer reactions within biological systems. They serve as electron carriers, shuttling electrons between different redox-active proteins in metabolic processes such as respiration and photosynthesis. Rubredoxins can efficiently transfer electrons to other redox partners as they readily alternate between the reduced and oxidized forms.
The rubredoxin cluster, which is typically coordinated to a single iron atom, is bound within the protein through coordination bonds with cysteine residues. This iron-sulfur cluster confers the characteristic red color to rubredoxins, hence their name. The redox properties of the cluster are crucial for the efficient electron transfer capabilities of rubredoxins.
Rubredoxins have been extensively studied due to their significance in various biological pathways. Their structures have been determined using various techniques such as X-ray crystallography, allowing for a deep understanding of their molecular mechanisms. By examining and manipulating rubredoxins, researchers aim to gain insights into electron transfer processes, enzymatic reactions, and the overall functioning of biological systems.

Etymology of RUBREDOXINS
The word rubredoxins has its etymology rooted in Greek and Latin.
The term can be broken down into two parts: rubro and doxin.
The prefix rubro is derived from the Latin word rubrum, meaning red. This is in reference to the red color of rubredoxins, which arise from the presence of iron-sulfur clusters in their structure that absorb light in the red color range.
The suffix doxin is derived from the Greek word doxa, meaning glory or splendor. This suffix is often used in scientific terminology to indicate a class or group of substances. Therefore, rubredoxins can be interpreted as red substances of glory or red substances of splendor.
