Ferrochelatase catalyses the eighth and terminal step in the biosynthesis of heme, converting protoporphyrin IX into heme B
Protoporphyrin ferrochelatase (EC 4.98.1.1, formerly EC 4.99.1.1, or ferrochelatase; systematic name protoheme ferro-lyase (protoporphyrin-forming)) is an enzyme encoded by the FECH gene in humans. Ferrochelatase catalyses the eighth and terminal step in the biosynthesis of heme, converting protoporphyrin IX into heme B. It catalyses the reaction: protoheme + 2 H+ = protoporphyrin + Fe2+ Function Ferrochelatase catalyzes the insertion of ferrous iron into protoporphyrin IX in the heme biosynthesis…

CBP has two critical mechanisms by which it is able to regulate gene expression: as an acetyltransferase, and as a protein scaffold
This gene is ubiquitously expressed and is involved in the transcriptional coactivation of many different transcription factors. CBP has two critical mechanisms by which it is able to regulate gene expression: as an acetyltransferase, and as a protein scaffold that helps recruit and construct the complexes that are necessary for transcription or chromatin remodeling. Phosphorylation of CBP increases…

Tryptophan tryptophylquinone (TTQ) formation
Tryptophan tryptophylquinone (TTQ) is an enzyme cofactor, generated by posttranslational modification of amino acids within the protein. Methylamine dehydrogenase (MADH), an amine dehydrogenase, requires TTQ for its catalytic function. From Wikipedia where this page was last updated June 22, 2022 See also Amicyanin is a type I copper protein that plays an integral role in electron transfer. In bacteria such as Paracoccus denitrificans, amicyanin is part of a three-member redox complex, along…
