Takara Identifies New RNAi-Related Enzymes

Japanese drug maker Takara Bio said last week that it has discovered seven new RNAi enzymes.

According to the company, the enzymes, which were discovered by screening various bacteria, can identify and cleave specific sequences of single-stranded RNAs. Takara also said that one of the enzymes, MazF, can impact HIV infection by inducing apoptosis in cells that have had Tat genes introduced.

Takara said that it sees the enzymes being used for HIV gene therapy, a single protein production system that enables targeted proteins to be produced, and reagents for RNA engineering.

Details about the enzymes will be presented at the 28th Annual Meeting of the Molecular Biology Society of Japan to be held Dec. 7-10, the company added.
