Enzymes must bind their substrates before they can catalyse any chemical reaction. Enzymes are usually very specific as to what substrates they bind and then the chemical reaction catalysed. Specificity is achieved by binding pockets with complementary shape, charge and hydrophilic/hydrophobic characteristics to the substrates. Enzymes can therefore distinguish between very similar substrate molecules to be chemoselective, regioselective and stereospecific. Webb21 juli 2024 · The first step in DNA replication is to ‘unzip’ the double helix structure of the DNA molecule.; This is carried out by an enzyme called helicase which breaks the hydrogen bonds holding the complementary bases of DNA together (A with T, C with G).; The separation of the two single strands of DNA creates a ‘Y’ shape called a replication ‘fork’.
