Continuous use of glycomacropeptide in the nutritional management of patients w...
Pena, MJ; Pinto, A; de Almeida, MF; Barbosa, CD; Ramos, PC; Rocha, S; Guimas, A; Ribeiro, R; Martins, E; Bandeira, A; Dias, CC; MacDonald, ABackground In phenylketonuria (PKU), modified casein glycomacropeptide supplements (CGMP-AA) are used as an alternative to the traditional phenylalanine (Phe)-free L-amino acid supplements (L-AA). However, studies focusing on the long-term nutritional status of CGMP-AA are lacking. This retrospective study evaluated the long-term impact of CGMP-AA over a mean of 29 months in 11 patients with a mean age at CGMP-...
Regulatory mechanisms controlling biogenesis of ubiquitin and the proteasome
London, MK; Keck, BI; Ramos, PC; Dohmen, RHAnalysis of several Saccharomyces cerevisiae ump mutants with defects in ubiquitin (Ub)-mediated proteolysis yielded insights into the regulation of the polyubiquitin gene UB14 and of proteasome genes. High-molecular weight Ub-protein conjugates accumulated in ump mutants with impaired proteasome function with a concomitant decrease in the amount of free Ub. In these mutants, transcriptional induction of UB14 w...
