A thermophilic lipase of Bacillus thermoleovorans ID-1 was cloned and sequenced. The lipase gene codes 416 amino acid residues and contains the conserved pentapeptide Ala-X-Ser-X-Gly as other Bacillus lipase genes. The optimum temperature of the lipase is 75 degrees C, which is higher than other known Bacillus lipases. For expression in Escherichia coli,(More)
This study was undertaken to determine the genotype variability of human metapneumovirus (hMPV) and its circulation pattern over a 3.5-year period, and to evaluate its clinical characteristics in Korean children. We investigated 4599 pediatric patients who were referred for a routine respiratory virus test by RT-PCR. hMPV genotype analyses were performed(More)
We report a 39-year-old woman with chorea-acanthocytosis (ChAc) who was referred with refractory hyperkinetic movement and truncal bending spasm. She was diagnosed with ChAc with clinical features and laboratory findings of acanthocytosis in peripheral blood smear, and genetic studies revealed novel mutations in the VPS13 gene. Because her symptoms did not(More)
In the presence of vaporized p-cresol, Pseudomonas alkylphenolia KL28 forms specialized aerial structures (SAS). A transposon mutant of strain KL28 (C23) incapable of forming mature SAS was isolated. Genetic analysis of the C23 mutant revealed the transposon insertion in a gene (ssg) encoding a putative glycosyltransferase, which is homologous to the(More)
BACKGROUND Although leucine-rich repeat kinase 2 (LRRK2) is the gene most commonly linked to autosomal dominant inherited Parkinson's disease (PD), there have been few reports in Asia, probably because of population-specific differences in allele frequencies. METHODS We identified a large Korean PD family with the p.Tyr1699Cys mutation in LRRK2 and(More)
Edwards syndrome, also called trisomy 18, is one of the most common autosomal anomalies. The survival rate of patients with Edwards syndrome is very low and its characteristic findings include cardiac malformations, mental retardation, growth retardation, specific craniofacial anomalies, clenched hands, rocker-bottom feet, and omphalocele. Compared with the(More)
The association of thymoma with pure red cell aplasia has been well documented, but amegakaryocytic thrombocytopenia is not a recognized paraneoplastic syndrome complicating thymoma. We report a case of thymoma-complicated pure red cell aplasia and amegakaryocytic thrombocytopenia in a 73-yr-old woman. Pure red cell aplasia was diagnosed seven months after(More)
With globalization, foreign patients are frequently encountered at the clinical practice in Korea. As the number of migrant workers from Southeast Asia has been notably rising since the late 1990's, unfamiliar tropical infectious diseases that they bring out, may give great challenges to the routine clinical practice in Korea. Melioidosis is a(More)
Congenital chloride diarrhea (CLD) is an autosomal recessive disorder with the hallmark of persistent watery Cl(-)-rich diarrhea from birth. Mutations in the solute carrier family 26, member 3 (SLC26A3) gene, which encodes a coupled Cl(-)/HCO(3)(-) exchanger in the ileum and colon, are known to cause CLD. Although there are a few reports of CLD patients in(More)
