Cupredoxin superfamily; Cupredoxins contain type I copper centers and are involved in inter-molecular electron transfer reactions. Cupredoxins are blue copper proteins, having an intense blue color due to the presence of a mononuclear type 1 (T1) copper site. Structurally, the cupredoxin-like fold consists of a beta-sandwich with 7 strands in 2 beta-sheets, which is arranged in a Greek-key beta-barrel. Some of these proteins have lost the ability to bind copper. The majority of family members contain multiple cupredoxin domain repeats: ceruloplasmin and the coagulation factors V/VIII have six repeats; laccase, ascorbate oxidase, 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.

 27-126 3.75e-50

Mavicyanin is a subclass of phytocyanins, a plant blue copper protein; Mavicyanin is a glycosylated protein isolated from Cucurbita pepo medullosa (zucchini) peelings. It belongs to the phytocyanin family of blue copper proteins, a ubiquitous family of plant cupredoxins. Mavicyanin is involved in electron transfer reactions with the Cu center transitioning between the oxidized Cu(II) form and the reduced Cu(I) form. The copper is tetrahedrally coordinated by a cysteine, 2 histidines, and a glutamine residue, like in the case of stellacyanin. The biological roles of mavicyanin have not been elucidated yet.

Phytocyanins are plant blue or type I copper proteins; Phytocyanins are plant blue or type I copper proteins. They are involved in electron transfer reactions with the Cu center transitioning between the oxidized Cu(II) form and the reduced Cu(I) form. Phytocyanins are classified into four groups: stellacyanin, plantacyanin, uclacyanin and early nodulin groups. Stellacyanin appears to be associated with the plant cell wall; it may be involved in oxidative reactions to build polymeric material making up the cell wall. Plantacyanin is shown to play a role in reproduction in Arabidopsis. Plantacyanins may also be stress-related proteins and may be involved in plant defense responses. The early nodulin-like protein (OsENODL1) from Oryza sativa is expressed specifically at the late developmental stage of the seeds.

The copper is tetrahedrally coordinated by a cysteine, 2 histidines, and a glutamine residue. The glutamine residue substitutes for a methione ligand typically found in other blue copper proteins. The exact function of stellacyanin is unknown. However, stellacyanin appears to be associated with the plant cell wall; it may be involved in oxidative reactions to build polymeric material making up the cell wall.
