Usually there are three kinds of proteins that could bind to an enzyme to enhance its catalytic activity. The prosthetic groups are one that are firmly attched to the enzymes. The best example of a prosthetic group is heme that is bound to hemoglobin.
The next is co factor, that could dissociate itself from the enzyme, like NADH and NADPH.
Cofactor, finally, are metal ions, usually cations, that bind to the metal ions and enhance the activity. they perform certain functions; as to hold the substrates in close proximity. The best example is DNA and RNA polymerase, where the upcoming nucleotide is held in the catalytic cleft of polymerase by Magnesium ions.
What else can I help you with?
Which term refers to a macromolecule that attaches to an enzyme and plays a helper role in catalysis?
A cofactor refers to a macromolecule that attaches to an enzyme to assist in catalysis. This can be a metal ion or a coenzyme.
Does maltase need a cofactor or activator?
Maltase does not require a cofactor or activator for its function. It is an enzyme that is able to catalyze the hydrolysis of maltose into glucose without the need for additional molecules to assist in the reaction.
Is an inorganic molecule a cofactor?
Metals ions are frequently cofactors of proteins.
How does membrane cofactor protein stop complement activation?
Membrane cofactor protein (MCP) acts as a cofactor for Factor I, which degrades C3b and C4b proteins, thus preventing the amplification of complement activation. By accelerating the decay of C3 convertases, MCP helps regulate the complement system and protect host cells from excessive complement-mediated damage.
A vitamin attached to a protein molecule forms an enzyme that can serve as a catalyst for reactions such as blood clotting?
This type of enzyme is called a cofactor, where the protein part is the enzyme and the vitamin is the cofactor. In this specific example, the vitamin likely acts as a cofactor by assisting the enzyme in catalyzing the blood clotting reaction. Cofactors are essential for the proper functioning of many enzymes in the body.
When was Cofactor Genomics created?
Cofactor Genomics was created in 2008.
Is ribosome a cofactor?
No .
What is The protein portion of an enzyme that is lacking a cofactor is called?
An apoenzyme or an apoprotein is the protein portion of an enzyme that lacks a cofactor. It becomes active when it combines with a cofactor to form a holoenzyme or a holoprotein.
What is a non-protein helper of an enzyme molecule called?
A non-protein helper of an enzyme molecule is called a cofactor. Cofactors can be either inorganic ions (like metal ions) or organic molecules (like coenzymes) that assist enzymes in catalyzing chemical reactions.
What is apoenzyme?
Apoenzyme is the protein portion of an enzyme, which is inactive without its cofactor or coenzyme. The binding of the cofactor or coenzyme to the apoenzyme forms the active enzyme, allowing it to catalyze a specific biochemical reaction.
Which ion is a cofactor in blood clotting?
calcium
What is the resulting value from the factor?
It is known as the cofactor.
What do kinases typically require as a cofactor?
Magnesium
Molecule which assists an enzyme?
Cofactor or coenzyme if organic
What are some enzyme co factors?
One is cofactor A.
Which term refers to a macromolecule that attaches to an enzyme and plays a helper role in catalysis?
A cofactor refers to a macromolecule that attaches to an enzyme to assist in catalysis. This can be a metal ion or a coenzyme.
What is a cofactor of a determinant?
The cofactor is the signed minor of a determinant, used to evaluate the determinant. You take the minor of the element - call that element aij - and if i + j is even, the cofactor is the minor - otherwise, it's the opposite of the minor. Thus, take the matrix, remove the row and column the element is in, and if the sum of the row number and column number is even, then there's your cofactor; otherwise, it's the additive inverse. For example, the cofactor of a34 is the determinant of the same matrix with the 3rd row and 4th column removed, and then you take the opposite (additive inverse or negative), because 3 + 4 = 7 is odd.
