Related Party Transactions [Abstract]
Related Party	Related Party AstraZeneca PLC Pam P. Cheng, a member of our board of directors for a three-year term expiring at our Annual Shareholder Meeting in June 2020, joined AstraZeneca PLC as Executive Vice President, Operations and Information Technology in June 2015. We sell biocatalyst products to AstraZeneca PLC and its controlled purchasing agents and contract manufacturers. We recognized $20 thousand and $0.1 million in revenue in the three and six months ended June 30, 2020, respectively, compared to $0.4 million and $0.4 million in the three and six months ended June 30, 2019, respectively, from transactions with AstraZeneca PLC and its controlled purchasing agents and contract manufacturers. At June 30, 2020 and December 31, 2019, we had nominal and $0.3 million, respectively, of receivables from AstraZeneca PLC and its controlled purchasing agents and contract manufacturers, respectively. Molecular Assemblies, Inc. In June 2020, we entered into a Stock Purchase Agreement with Molecular Assemblies, Inc (“MAI”) pursuant to which we purchased 1,587,050 shares of Series A preferred stock for $1.0 million in MAI and, concurrently with our initial equity investment, John Nicols, our chief executive officer, joined MAI’s board of directors. At the same time, we entered into a Master Collaboration and Research Agreement (the “MAI Agreement”) with MAI to engineer DNA polymerase enzymes to deliver differentiated and cost-effective solutions for the enzymatic synthesis of DNA. Under the MAI Agreement and its related statement of work (“SOW”), we will apply our CodeEvolver^® protein engineering platform technology to improve the DNA polymerase enzymes that are critical for enzymatic DNA synthesis. Based on these services, we are eligible to earn additional Series A preferred stock of MAI. MAI will combine its advanced chemistries with our enzymes to drive the process to commercialization. Under the MAI Agreement and its associated SOW, we will engage in research and development activities to engineer DNA polymerase enzymes for the enzymatic synthesis of DNA and will receive monthly fees in the form of shares of Series A preferred stock in MAI. Such non-monetary payments will be earned over ten to thirteen months and issued thirty days in arrears after each calendar quarter-end. We are also eligible to receive amounts for bonuses, targets and milestones on achievement of timeline and project goals specified in the SOW. Payments for bonuses, targets and milestones on achievement of timeline and project goals are to be issued thirty days after the Company provides notification of completion. Under the MAI Agreement, we will have the right to use and sell the engineered enzymes to third parties for any purpose other than for the synthesis of native DNA. Under the MAI Agreement, we would make a $0.5 million payment to MAI on meeting a milestone of $5.0 million in aggregate commercial sales by the Company to third parties of the engineered enzymes or any product incorporating or derived from the engineered enzymes for any purpose other than the synthesis of native DNA. The MAI Agreement contemplates that we and MAI will enter into a Commercialization and Enzyme Supply Agreement (the “CESA”) within six months following the completion of certain timelines specified in the SOW. In addition, we and MAI have agreed pursuant to the MAI Agreement to certain terms to be contained within the CESA in the event that the CESA becomes executed in the future. Those include: (a) that MAI would receive an exclusive license to use the DNA polymerase enzymes engineering by us under the MAI Agreement in the synthesis of native DNA and a non-exclusive license to use these enzymes for research and development on the synthesis of non-native DNA, and (b) that we would become the exclusive manufacturer of these enzymes for MAI, its affiliates and licensees. We recognized no research and development revenue in the three and six months ended June 30, 2020 from transactions with MAI.
