HERC1
Probable E3 ubiquitin-protein ligase HERC1 is an enzyme that in humans is encoded by the ''HERC1'' gene In biology, the word gene (from , ; "... Wilhelm Johannsen coined the word gene to describe the Mendelian units of heredity..." meaning ''generation'' or ''birth'' or ''gender'') can have several different meanings. The Mendelian gene is a b .... The protein encoded by this gene stimulates guanine nucleotide exchange on ARF1 and Rab proteins. This protein is thought to be involved in membrane transport processes Knowledge of the gene is facilitated by the discovery of a mouse mutation. The tambaleante (tbl) mutation arose spontaneously on the DW/J-Pas genetic background, a recessive mutation of the Herc1 gene located on mouse chromosome 9 that increases Herc1 protein levels. This protein is largely expressed in many tissues (Sanchez-Tena et al., 2016; https://www.proteinatlas.org/ENSG00000103657-HERC1/tissue) and multiple brain regions including the cerebellum (https:// ...

Enzyme
Enzymes () are proteins that act as biological catalysts by accelerating chemical reactions. The molecules upon which enzymes may act are called substrate (chemistry), substrates, and the enzyme converts the substrates into different molecules known as product (chemistry), products. Almost all metabolism, metabolic processes in the cell (biology), cell need enzyme catalysis in order to occur at rates fast enough to sustain life. Metabolic pathways depend upon enzymes to catalyze individual steps. The study of enzymes is called ''enzymology'' and the field of pseudoenzyme, pseudoenzyme analysis recognizes that during evolution, some enzymes have lost the ability to carry out biological catalysis, which is often reflected in their amino acid sequences and unusual 'pseudocatalytic' properties. Enzymes are known to catalyze more than 5,000 biochemical reaction types. Other biocatalysts are Ribozyme, catalytic RNA molecules, called ribozymes. Enzymes' Chemical specificity, specific ...
