This entry represents the beta-barrel domain found in CREG (cellular repressor of E1A-stimulated genes) proteins from animals and closely homologues from plants, fungi and bacteria [1]. CREG is a secreted glycoprotein that inhibits proliferation and enhances differentiation of human embryonal carcinoma cells. It forms a tight homodimer that, unlike related structural homologues it does not bind flavin mononucleotide as the putative flavin mononucleotide-binding pocket in CREG is sterically blocked by a loop and several key bulky residues [1]. The structure of this domain from bacterial and plant proteins revealed that it is involved in heme binding, such as Swiss:A0R6E4 and Swiss:Q8LDU1 [2,3].
This domain is found in a group of putative heme-iron utilisation proteins, such as HugZ. It can also be found in C-terminal of the glutamyl-tRNA reductase-binding (GluTRBP) protein from Arabidopsis [1]. GluTRBP is involved in the regulation of gluta ...
This domain is found in a group of putative heme-iron utilisation proteins, such as HugZ. It can also be found in C-terminal of the glutamyl-tRNA reductase-binding (GluTRBP) protein from Arabidopsis [1]. GluTRBP is involved in the regulation of glutamyl-tRNA reductase (GluTR) which is important for the synthesis and distribution of 5-aminolevulinate, a precursor in heme and chlorophyll biosynthesis [2]. GluTRBP is necessary for efficient photosynthetic electron transport in chloroplasts [3].
