Adenosylhomocysteinase (EC 3.13.2.1, S-adenosylhomocysteine synthase, S-adenosylhomocysteine hydrolase, adenosylhomocysteine hydrolase, S-adenosylhomocysteinase, SAHase, AdoHcyase) is an enzyme that catalyzes the nicotinamide adenine dinucleotide (NAD +) dependent, reversible hydrolysis of S-adenosylhomocysteine to homocysteine and adenosine.
Mutations in the human sonic hedgehog gene SHH cause holoprosencephaly type 3 HPE3, as a result of the loss of the ventral midline. The sonic hedgehog transcription pathway has also been linked to the formation of specific kinds of cancerous tumors, including the embryonic cerebellar tumor [ 30 ] and medulloblastoma , [ 31 ] as well as the ...

Mutations in mitochondrial DNA are inherited from the mother, i.e. they are passed on through the female line. In cases where a mitochondrial mutation has occurred, a patient will carry a mixture of the mutated, damaged DNA, and the normal DNA, in varying proportions in different cells (a phenomenon known as heteroplasmy ); the severity of the ...
Here’s what experts have to say about berberine supplements. Some small studies have shown that low levels of glutathione may be linked to poor health and tend to decline with age. This is ...
NAD+ supplements, IV drips, and injections have gained a lot of traction on social media due to their supposed anti-aging benefits. Here, doctors reveals the truth behind the trend.
Site-directed mutagenesis is used to generate mutations that may produce a rationally designed protein that has improved or special properties (i.e.protein engineering). Investigative tools – specific mutations in DNA allow the function and properties of a DNA sequence or a protein to be investigated in a rational approach. Furthermore ...
