leber hereditary optic neuropathy (lhon) is a maternally inherited form of retinal ganglion cell degeneration leading to optic atrophy in young adults. it is caused by three primary point mutations including g11778a, g3460a, and t14484c in the mitochondrial genome. these three mutations account for the majority of lhon cases and affect genes that encode for different subunits of mitochondrial c...

Abstract Microorganisms are natural biocatalysts capable of automatic selection and adaptation for wastewater treatment with any content organic pollutants. Microbiological destruction a wide range polycarbon compounds occurs due to the formation microbial sequence. The sequence is that end products (exometabolites) “primary” destructor-microorganisms primary substrates “secondary” destructor-m...

The amino-terminal region of the enterotoxin of Clostridium perfringens was investigated by automated sequence analysis. The primary structure results revealed that the enterotoxin is composed of a single polypeptide amino acid sequence. Computer comparison of a 20-residue sequence with a sequence library of reported proteins revealed no significant chemical similarities, indicating that the en...
