WebbThe two sub-units are unequal in size and exist in this state until required for use. The larger sub-unit is about twice as large as the smaller one. The larger sub-unit has mainly a catalytic function; the smaller sub-unit mainly a decoding one. In the large sub-unit ribosomal RNA performs the function of an enzyme and is termed a ribozyme.

In the field of biochemistry, the specificity constant (also called kinetic efficiency or ), is a measure of how efficiently an enzyme converts substrates into products. A comparison of specificity constants can also be used as a measure of the preference of an enzyme for different substrates (i.e., substrate specificity). The higher the specificity constant, the more the enzyme "prefers" that substrate. shanghai evergreen agro chemical co ltdWebb26 nov. 2024 · Monomers are the smaller units from which larger molecules are made.
