Methionine overproduction by Saccharomycopsis lipolytica.
Six ethionine-resistant (Etr) regulatory mutants of Saccharomycopsis lipolytica Sl/1 overproducing methionine have been isolated. Five of them are also resistant to seleno-methionine. The activity of homocysteine synthase (O-acetyl-L-hormoserine-acetate lyase, adding hydrogen sulfide) is derepressed in these mutants and is not susceptible to the methionine-mediated repression. The pool of free ...
متن کاملDisruption of gene YlODC reveals absolute requirement of polyamines for mycelial development in Yarrowia lipolytica.
Polyamines are required for cellular growth and differentiation. In mammals and fungi they are synthesized via a pathway involving ornithine decarboxylase (ODC), which transforms ornithine into putrescine. We have cloned and disrupted the gene coding for ODC in Yarrowia lipolytica to analyze the role of polyamines in dimorphism of this fungus. Substrate- and cofactor-binding motifs, as well as ...

T he intensive care unit (ICU) is an extremely stressful environment where anxiety is prevalent, pain frequent, rest difficult, and sleep often impossible. Relief of pain and anxiety is often neglected while efforts focus on immediate life-threatening concerns. A growing awareness of ICU imposed stress and the increasing popularity of some modes of mechanical ventilation such as extended ratio ...
متن کاملAnalysis of factors causing hyperkalemia.
OBJECTIVE Patients with impaired renal function or diabetes are considered to be prone to hyperkalemia. Furthermore, hyperkalemia is an adverse drug reaction of inhibitors of the renin-angiotensin system (RAS) that are established to be efficacious in these patients. However, the current status of hyperkalemia in the clinical setting remains obscure. METHODS A total of 9,117 patients treated ...
