Details

Cytochromes c (cytC) can be defined as electron-transfer proteins.This data set describes the phylogenetic relationships of cytC of mitochondria and bacteria. G-protein-coupled receptors, GPCRs, constitute a vast protein family that encompasses a wide range of functions (including various autocrine, paracrine and endocrine processes). The rhodopsin-like GPCRs themselves represent a widespread protein family that includes hormone, neurotransmitter and light receptors.
