Cytochrome is a heme-containing subunit of the cytochrome b-c1 complex, which accepts electrons from Rieske protein and transfers electrons to cytochrome c in the mitochondrial respiratory chain. [1] It is formed in the cytosol and targeted to the mitochondrial intermembrane space. Cytochrome c1 belongs to the cytochrome c family of proteins.

Cytochrome c is a highly conserved protein across the spectrum of eukaryotic species, found in plants, animals, fungi, and many unicellular organisms. This, along with its small size (molecular weight about 12,000 daltons), [7] makes it useful in studies of cladistics. [8] Cytochrome c has been studied for the glimpse it gives into evolutionary ...
CYC1 encodes a protein that is located in the inner mitochondrial membrane and is part of Ubiquinol Cytochrome c Reductase (complex III).The encoded protein, CYC1, is a respiratory subunit of the cytochrome bc1 complex, which plays an important role in the mitochondrial respiratory chain by transferring electrons from the Rieske iron-sulfur protein to cytochrome c.
A C1-INH concentrate can be used for angio-oedema (C1-INH deficiency). [2] [3] Pneumococcus and Haemophilus infections can be prevented via immunization. [2] Epsilon-aminocaproic acid could be used to treat hereditary C1-INH deficiency, though the possible side effect of intravascular thrombosis should be weighed. [7]
Small soluble cytochrome c proteins with a molecular weight of 8-12 kDa and a single heme group belong to class I. [10] [11] It includes the low-spin soluble cytC of mitochondria and bacteria, with the heme-attachment site located towards the N-terminus, and the sixth ligand provided by a methionine residue about 40 residues further on towards the C-terminus.
C1-inhibitor plays the role of inactivating C1r and C1s to prevent further downstream classical complement activity. [13] [12] C1-inhibitor controls the processes involved in maintaining vascular permeability. As a result, C1-inhibitor levels of less than 50% of the standard lead to increased vascular permeability, characteristic of angioedema ...
Complement component 3 (C3) is a protein involved in both the innate and adaptive immune response. C3 is one of over 30 complement proteins circulating in the blood. [3] C3 circulates in an inactive form but can be activated in order to aid the immune system's response to a foreign invader. [4]
