Viral enzymes

an enzyme which generates DNA from an RNA template, a process termed reverse transcription

Retroviral integrase (IN) is an enzyme produced by a retrovirus (such as HIV) that integrates (forms covalent links between) its genetic information into that of the host cell it infects. Retroviral INs are not to be confused with phage integrases (recombinases) used in biotechnology, such as λ phage integrase, as discussed in site-specific recombination.

Lysins, also known as endolysins or murein hydrolases, are hydrolytic enzymes produced by host bacteria when infected with bacteriophages in order to cleave the cell wall during the final stage of the lytic cycle to release the viral particles. Lysins are highly evolved enzymes that are able to target one of the five bonds in peptidoglycan (murein), the main component of bacterial cell walls, which allows the release of progeny virions from the lysed cell. Cell-wall-containing Archaea are also lysed by specialized pseudomurein-cleaving lysins, while most archaeal viruses employ alternative mec
