Human genes coding for hypoxanthine phosphoribosyltransferase (HPRT, EC 2.4.2.8; IMP:pyrophosphate phosphoribosyltransferase), glucose-6-phosphate dehydrogenase (G6PD, EC 1.1.1.49; D-glucose-6-phosphate:NADP+ 1-oxidoreductase), and phosphoglycerate kinase (PGK, EC 2.7.2.3; ATP:3-phospho-D-glycerate 1-phosphotransferase) have been assigned to specific regions on the long arm of the X chromosome ...

introduction: in order to make a dimensional proportion between human and equipment or environment, anthropometric data bank is essential. anthropometry has an important role in industrial management and ergonomic design. this information is needed to be collected regularly in every society. the purpose of this study was to determine arm length to height ratio according to gender in adults, bet...

Genetic variations were studied for 13 accessions of Lolium multiflorum using cytogenetical traits. Karyotype was prepared for 5 metaphases cells of each accession and the traits of total length (TL), long arm (LA), short arm (SA), arm ratio (AR) and centromer index (CI) were determined by micromeasure software. Six accessions were diploid and seven accessions were tetraploid, the basic chromos...

Transfer RNA (tRNA) canonically has the clover-leaf secondary structure with the acceptor, D, anticodon, and T arms, which are folded into the L-shaped tertiary structure. To strengthen the L form, posttranscriptional modifications occur on nucleotides buried within the core, but the modification enzymes are paradoxically inaccessible to them in the L form. In this study, we determined the crys...

An amine bisphenol ligand with an ammonium iodide group in the pendant arm (H2L) reacts V, Mo and U oxometal precursors to form oxovanadium(V), dioxomolybdenum(VI) dioxouranium(VI) species, respectively. In methanol solutions, vanadium(V) molybdenum(VI) 1:1 complexes [VO(OMe)(L)]I·2MeOH [MoO2(L)(H2O)]I·2MeOH, where cationic charge is counterbalanced by anion. Uranium(VI) forms a complex which a...

Streptomyces linear chromosomes display various types of rearrangements after telomere deletion, including circularization, arm replacement, and amplification. We analyzed the new chromosomal deletion mutants Streptomyces griseus 301-22-L and 301-22-M. In these mutants, chromosomal arm replacement resulted in long terminal inverted repeats (TIRs) at both ends; different sizes were deleted again...

a binuclear macrocyclic ligand containing dissimilar n(amine)2o2 and n(imine)2o2 coordination sites sharing two phenolic oxygen atoms, was prepared by cyclic condensation of dialdehyde precursor l1h2 with 1,3-diaminopropane. the ligand includes two propionitrile pendant arms on the amine nitrogen atoms. the homobimetallic complex [znl2zn(oac)]pf6 was synthesized by one step procedure. heterobim...
