 Synonyms & Historicals
Enzyme Precursors .
Precursors, Enzyme .
Proenzymes .
Zymogens .
Physiologically inactive substances that can be converted to active enzymes. .
/enzymology .
/enzyme activity .
/enzymes .
Used with organisms, except vertebrates, and with organs and tissues. It is also used with diseases for enzymes during the course of the disease, but excludes diagnostic enzyme tests, for which "diagnosis" is used. .
Enzymes .
Biocatalysts .
Biological molecules that possess catalytic activity. They may occur naturally or be synthetically created. Enzymes are usually proteins, however CATALYTIC RNA and CATALYTIC DNA molecules have also been identified. .

RNA, Small Nuclear, Precursors .
RNA, Transfer, Precursors .
RNA transcripts of the DNA that are in some unfinished stage of post-transcriptional processing (RNA PROCESSING, POST-TRANSCRIPTIONAL) required for function. RNA precursors may undergo several steps of RNA SPLICING during which the phosphodiester bonds at exon-intron boundaries are cleaved and the introns are excised. Consequently a new bond is formed between the ends of the exons. Resulting mature RNAs can then be used; for example, mature mRNA (RNA, MESSENGER) is used as a template for protein production. .
Prodrugs .
Pro-Drugs .
Precursors, Drug .
Pro Drugs .
Drug Precursors .
A compound that, on administration, must undergo chemical conversion by metabolic processes before becoming the pharmacologically active drug for which it is a prodrug. .
