Human lactate dehydrogenase (LDH)-A mutant gene was analyzed by polymerase chain reaction - DNA conformation polymorphism (DCP). We used polyacrylamide gradient gel and silver staining procedures for DCP analysis and observed abnormal migration patterns in individuals heterozygous for LDH-A deficiency. Further sequence determination of the mutant alleles consistently resulted in detection of base substitutions, a G to T transversion at codon 328 (GAG----TAG), and synonymous substitutions at codon 115, 160 and 172. Such mutations were easily detectable using the DCP technique. The DCP technique using the polyacrylamide gradient gel and silver staining method seems likely to be useful for the rapid screening of mutations and for further genotype detection.
Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose.
The chemical reactions and pathways involving carbohydrates, any of a group of organic compounds based of the general formula Cx(H2O)y, as carried out by individual cells.
Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an extracellular stimulus.
The chemical reactions and pathways resulting in the breakdown of a monosaccharide (generally glucose) into pyruvate, with the concomitant production of a small amount of ATP. Glycolysis begins with phosphorylation of a monosaccharide (generally glucose) on the sixth carbon by a hexokinase, and ends with the production of pyruvate. Pyruvate may be converted to ethanol, lactate, or other small molecules, or fed into the TCA cycle.

Protein involved in the anaerobic enzymatic conversion of glucose to lactate or pyruvate, resulting in energy stored in the form of adenosine triphosphate (ATP), as occurs in skeletal muscle and in embryonic tissue.
A reference proteome is a set of protein sequences derived from a complete proteome which constitutes a defined standard for a particular user community. Reference proteomes are manually defined according to a number of criteria. They cover the proteomes of well- studied model organisms and other proteomes of interest for biomedical and biotechnological research. Reference proteomes have been selected to provide broad coverage of the tree of life, and constitute a representative cross-section of the taxonomic diversity to be found within UniProtKB.
