Engineered imine reductases and methods for the reductive animation of ketone and amine compounds.

Codexis, Inc.

A patent family: one line of work, grouped by real continuity rather than by a technology label inferred from titles. 16 of these applications claim priority to application 61/646,100, filed May 11, 2012. A shared origin can cover several different claimed inventions, which is why members here may not share a title. In-force patents first, soonest term end first, then patent number. Expired patents follow, in the same order.
