In linear algebra, a minor of a matrix A is the determinant of some smaller square matrix, cut down from A by removing one or more of its rows and columns. Minors obtained by removing just one row and one column from square matrices (first minors) are required for calculating matrix cofactors, which in turn are useful for computing both the determinant and inverse of square matrices. Earlier (Section ), we considered the fact that many enzymes re- quire cofactors to be catalytically active. One class of these cofactors, termed coenzymes, consists of small organic molecules, many of which are derived from vitamins. Vitamins themselves are organic molecules that are needed in small amounts in the diets of some higher : Jeremy M Berg, John L Tymoczko, Lubert Stryer.

  Some cofactors are ions such as Ca ++, Mg ++, and K +; other cofactors are organic molecules called coenzymes which serve as carriers for chemical groups or electrons. NAD +, NADP +, FAD, and coenzyme A (CoA) are examples of coenzymes. Figure \(\PageIndex{4}\): An apoenzyme and cofactor combine to form a haloenzyme. Cofactors are inorganic ions such as iron (Fe++) and magnesium (Mg++). One example of an enzyme that requires a metal ion as a cofactor is the enzyme that builds DNA molecules, DNA polymerase, which requires a bound zinc ion (Zn++) to function.

  Many enzymes are simple proteins consisting entirely of one or more amino acid chains. Other enzymes contain a nonprotein component called a cofactor that is necessary for the enzyme’s proper are two types of cofactors: inorganic ions [e.g., zinc or Cu(I) ions] and organic molecules known as coenzymes.   The cofactors and coenzymes (organic cofactors) that help enzymes catalyze reactions Watch the next lesson:

So cofactors are the number you get when you eliminate the row and column of a designated element in a matrix, which is just a grid in the form of a square or a rectangle.

The cofactor is always preceded by a negative (-) or a positive (+) sign, depending on whether the number is in a + or – position. Section Cofactor Expansions permalink Objectives. Learn to recognize which methods are best suited to compute the determinant of a given matrix.

Recipes: the determinant of a 3 × 3 matrix, compute the determinant using cofactor expansions. Vocabulary words: minor, cofactor. In this section, we give a recursive formula for the determinant of a matrix, called a cofactor expansion.

Cofactor, a component, other than the protein portion, of many enzymes. If the cofactor is removed from a complete enzyme (holoenzyme), the protein component (apoenzyme) no longer has catalytic activity.

A cofactor that is firmly bound to the apoenzyme and cannot be removed without denaturing the latter is termed a prosthetic group; most such groups contain an atom of metal such as copper or iron. The longest running serial published by Academic Press continues its well-respected run with Vol a special volume in which a guest editor has come on board and has assembled some well-known contributors who are international authorities in the field.

Together they tackle some of the latest topics in the field such as riboflavin and folate biosynthesis, biotin and lipoic acid. These three dehydrogenases also require the co-factors derived from the vitamins lipoic acid, pantothenic acid (CoA), riboflavin, and niacin.

For this reason these three dehydrogenases are often referred to as the T ender (thiamine) L oving (lipoic acid) C are (CoA) F or (flavin) N ancy (niacin) enzymes. The cofactor may aid in the catalytic function of an enzyme, as do metals and prosthetic groups, or take part in the enzymatic reaction, as do coenzymes.

Protein - Protein - Cofactors: Although some enzymes consist only of protein, many are complex proteins; i.e., they have a protein component and a so-called cofactor.
