Enzymes which regulate the metabolic reactions for sustaining all living things, are the engines of life. The discovery of molecules that are able to control enzyme activity is of great interest for therapeutics and the biocatalysis industry. Peptides are promising enzyme modulators due to their large chemical diversity and the existence of well-established methods for library synthesis. Microarrays represent a powerful tool for screening thousands of molecules, on a small chip, for candidates that interact with enzymes and modulate their functions. In this work, a method is presented for screening high-density arrays to discover peptides that bind and modulate enzyme …

The highly specialized telomerase ribonucleoprotein enzyme is composed minimally of telomerase reverse transcriptase (TERT) and telomerase RNA (TR) for catalytic activity. Telomerase is an RNA-dependent DNA polymerase that syntheizes DNA repeats at chromosome ends to maintain genome stability. While TERT is highly conserved among various groups of species, the TR subunit exhibits remarkable divergence in primary sequence, length, secondary structure and biogenesis, making TR identification extremely challenging even among closely related groups of organisms. A unique computational approach combined with in vitro telomerase activity reconstitution studies was used to identify 83 novel TRs from 10 animal kingdom phyla spanning 18 …
