Candida albicans, the most common fungal pathogen of humans, possesses an estrogen-binding protein (EBP) that binds mammalian estrogens with high affinity. We report here the cloning and complete nucleotide sequence of a gene encoding a C. albicans EBP. Amino acid sequences obtained from cyanogen bromide fragments of purified EBP were used to design(More)
Propionic acidemia is an inherited metabolic disease caused by the deficiency of the mitochondrial protein propionyl-CoA carboxylase (PCC), one of the four biotin-dependent enzymes. PCC is a multimeric protein composed of two different alpha- and beta-PCC subunits, nuclearly encoded by the PCCA and PCCB genes, respectively. Mutations in either gene cause(More)
Propionic acidemia (PA) is a recessive disorder caused by a deficiency of propionyl-CoA carboxylase (PCC), a dodecameric enzyme composed of two different proteins alpha-PCC and beta-PCC, nuclear encoded by the PCCA and PCCB genes, respectively. Mutations in either gene cause PA and to date, up to 47 different allelic variations in the PCCB gene have been(More)
Propionic acidaemia (PA) is an autosomal recessive disorder caused by mutations in either of the PCCA or PCCB genes which encode the alpha and beta subunits, respectively, of the mitochondrial enzyme propionyl-CoA carboxylase (PCC). In this work we have examined the biochemical findings and clinical outcome of 37 Spanish PA patients in relation to the(More)
Mutations in any of the three different genes BCKDHA, BCKDHB, and DBT encoding for the E1alpha, E1beta, and E2 catalytic components of the branched-chain alpha-ketoacid dehydrogenase (BCKD) complex can cause maple syrup urine disease (MSUD). The disease presents heterogeneous clinical and molecular phenotypes. Severity of the disease ranges from the(More)
Mutations in the PCCA or PCCB genes, encoding both subunits of propionyl-CoA carboxylase, result in propionic acidemia, a life-threatening inborn error of metabolism with autosomal recessive inheritance. To date, 41 mutations in the PCCA gene and 54 in the PCCB gene have been reported, most of them single base substitutions causing amino acid replacements,(More)
Mutations on the mitochondrial-expressed Branched Chain α-Keto acid Dehydrogenase Kinase (BCKDK) gene have been recently associated with a novel dietary-treatable form of autism. But, being a mitochondrial metabolism disease, little is known about the impact on mitochondrial performance. Here, we analyze the mitochondrial response to the BCKDK-deficiency in(More)
We report a 5-year-old boy with propionic acidaemia who developed a rapidly fatal necrosis of the basal ganglia after an episode of clinical deterioration. Neither metabolic acidosis nor hyperammonaemia were present. Organic acid analysis in both urine and CSF showed increased levels of methylcitric and 3-hydroxypropionic acids. Propionic acidaemia was(More)
Propionyl-CoA carboxylase (PCC) is a mitochondrial biotin-dependent enzyme composed of an equal number of alpha and beta subunits. Mutations in the PCCA (alpha subunit) or PCCB (beta subunit) gene can cause the inherited metabolic disease propionic acidemia (PA), which can be life threatening in the neonatal period. Lack of data on the genomic structure of(More)
This work examined nine patients with creatine deficiency syndrome (CDS): six with a creatine transport (CRTR) defect and three with a GAMT defect. Eleven nucleotide variations were detected: six in SLC6A8 and five in GAMT. These changes were analyzed at the mRNA level and specific alleles (most of which bore premature stop codons) were selected as nulls(More)
