The alteration of the fine-tuned balance of phospho/dephosphorylation reactions in the cell often results in functional disturbance. In the yeast Saccharomyces cerevisiae, the overexpression of Ser/Thr phosphatase Ppz1 drastically blocks cell proliferation, with a profound change in the transcriptomic and phosphoproteomic profiles.

The Ser/Thr protein phosphatase Ppz1 from Saccharomyces cerevisiae is the best characterized member of a family of enzymes only found in fungi. Ppz1 is regulated in vivo by two inhibitory subunits, Hal3 and Vhs3, which are moonlighting proteins also involved in the decarboxylation of the 4-phosphopantothenoylcysteine (PPC) intermediate required for coenzyme A biosynthesis.

37 p, 10.2 MB Cryptococcus neoformans can form titan-like cells in vitro in response to multiple signals / Trevijano-Contador, Núria (Centro Nacional de Microbiología (Espanya)) ; Oliveira, Haroldo César de (Universidade Estadual Paulista (UNESP). Departamento de Análises Clínicas) ; García-Rodas, Rocío (Centro Nacional de Microbiología (Espanya)) ; Rossi, Suélen Andreida (Centro Nacional de Microbiología (Espanya)) ; Llorente Muñoz, Irene (Centro Nacional de Microbiología (Espanya)) ; Zaballos, Ángel (Instituto de Salud Carlos III) ; Janbon, Guilhem (Institut Pasteur.

Institut de Biotecnologia i de Biomedicina "Vicent Villar Palasí"
Cryptococcus neoformans is an encapsulated pathogenic yeast that can change the size of the cells during infection. In particular, this process can occur by enlarging the size of the capsule without modifying the size of the cell body, or by increasing the diameter of the cell body, which is normally accompanied by an increase of the capsule too.

12 p, 2.4 MB Mutations at the hydrophobic core affect Hal3 trimer stability, reducing its Ppz1 inhibitory capacity but not its PPCDC moonlighting function / Santolaria Bello, Carlos (Universitat Autònoma de Barcelona.

Institut de Biotecnologia i de Biomedicina "Vicent Villar Palasí") ; Strauss, Erick (Stellenbosch University. Department of Biochemistry) ; Ariño Carmona, Joaquín (Universitat Autònoma de Barcelona. Departament de Bioquímica i de Biologia Molecular)
S. cerevisiae Hal3 (ScHal3) is a moonlighting protein that, is in its monomeric state, regulates the Ser/Thr protein phosphatase Ppz1, but also joins ScCab3 (and in some instances the Hal3 paralog Vhs3) to form an unusual heterotrimeric phosphopantothenoylcysteine decarboxylase (PPCDC) enzyme.

19 p, 4.0 MB Protein phosphatase Ppz1 is not regulated by a hal3-like protein in plant pathogen ustilago maydis / Zhang, Chunyi (Universitat Autònoma de Barcelona. Institut de Biotecnologia i de Biomedicina "Vicent Villar Palasí") ; de la Torre, Antonio. (Consejo Superior de Investigaciones Científicas (Espanya).

Ppz enzymes are type-1 related Ser/Thr protein phosphatases that are restricted to fungi. In S. cerevisiae and other fungi, Ppz1 is involved in cation homeostasis and is regulated by two structurally-related inhibitory subunits, Hal3 and Vhs3, with Hal3 being the most physiologically relevant.

14 p, 1.8 MB The yeast Aft2 transcription factor determines selenite toxicity by controlling the low affinity phosphate transport system / Pérez-Sampietro, Maria (Universitat de Lleida. Departament de Ciències Mèdiques Bàsiques) ; Serra Cardona, Albert (Universitat Autònoma de Barcelona. Departament de Bioquímica i de Biologia Molecular) ; Canadell, David (Universitat Autònoma de Barcelona. Institut de Biotecnologia i de Biomedicina "Vicent Villar Palasí") ; Casas, Celia (Universitat de Lleida.

Departament de Ciències Mèdiques Bàsiques)
The yeast Saccharomyces cerevisiae is employed as a model to study the cellular mechanisms of toxicity and defense against selenite, the most frequent environmental selenium form. We show that yeast cells lacking Aft2, a transcription factor that together with Aft1 regulates iron homeostasis, are highly sensitive to selenite but, in contrast to aft1 mutants, this is not rescued by iron supplementation.
