Protein Domain : Uncharacterized cupredoxin-like protein, Cyanobacteria-type IPR041716

Type  Domain
Description  This entry represents a group of uncharacterised proteins from Cyanobacteria that share protein sequence similarity with cupredoxin. Cupredoxins are blue copper proteins because they have an intense blue color due to the presence of a mononuclear type 1 (T1) copper site. Structurally, the cupredoxin-like fold consists of a β-sandwich with 7 strands in 2 β-sheets, which is arranged in a Greek-key β-barrel. Some of these proteins have lost the ability to bind copper. Majority of family members contain multiple cupredoxin domain repeats; ceruloplasmin and coagulation factors V/VIII have six repeats; Laccase, ascorbate oxidase, and spore coat protein A, and multicopper oxidase CueO contain three repeats; and nitrite reductase has two repeats. Others are mono-domain cupredoxins, such as plastocyanin, pseudoazurin, plantacyanin, azurin, rusticyanin, stellacyanin, quinol oxidase and the periplasmic domain of cytochrome c oxidase subunit II [ , ].
