Journal ArticleDOI
Purification, characterization, and amino acid sequence of cerato-platanin, a new phytotoxic protein from Ceratocystis fimbriata f. sp. platani.
TL;DR: A new phytotoxic protein (cerato-platanin) of about 12.4 kDa has been identified in culture filtrates of the Ascomycete Ceratocystis fimbriata f.
Journal ArticleDOI
Nitric oxide causes inactivation of the low molecular weight phosphotyrosine protein phosphatase.
Anna Caselli,Giovanni G. Camici,G. Manao,Gloriano Moneti,Luigia Pazzagli,Gianni Cappugi,Giampietro Ramponi +6 more
TL;DR: The findings on low M(r) and Yersinia PTPase are potentially interesting for all PTPases, an enzyme class that is involved in a number of important biological processes.
Journal ArticleDOI
The role of Cys12, Cys17 and Arg18 in the catalytic mechanism of low‐Mr cytosolic phosphotyrosine protein phosphatase
Paolo Cirri,Paola Chiarugi,Guido Camici,Giampaolo Manao,Giovanni Raugei,Gianni Cappugi,Giampietro Ramponi +6 more
TL;DR: Phosphoenzyme-trapping experiments enable us to identify Cys12 as the active-site residue that performs the nucleophilic attack at the phosphorus atom of the substrate to produce a phosphoenzyme covalent intermediate.
Journal ArticleDOI
The Structure of the Elicitor Cerato-platanin (CP), the First Member of the CP Fungal Protein Family, Reveals a Double ψβ-Barrel Fold and Carbohydrate Binding
Aline L. de Oliveira,Mariana Gallo,Luigia Pazzagli,Celso Eduardo Benedetti,Gianni Cappugi,Aniello Scala,Barbara Pantera,Alberto Spisni,Thelma A. Pertinhez,Daniel O. Cicero +9 more
TL;DR: The results suggest that CP might be involved in polysaccharide recognition and that the double ψβ-barrel fold is widespread in distantly related organisms, where it is often involved in host-microbe interactions.
Journal ArticleDOI
Response to cadmium in carrot in vitro plants and cell suspension cultures
Luigi Sanità di Toppi,Maurizio Lambardi,Luigia Pazzagli,Gianni Cappugi,Mauro Durante,R. Gabbrielli +5 more
TL;DR: In vitro grown plants and cell suspension cultures of carrot were treated with various Cd concentrations and absence of ethylene caused both a decrease in the phytochelatin synthase activity of cell suspensions and a strong lowering in the Cd-induced SH groups in plants.
