Misys Healthcare Systems — which earlier this year moved into a new, 122,000-square-foot facility at Williams Centre — has sold its Tucson business.
Vista Equity Partners, a private investment firm, is paying $381.5 million for Misys' diagnostic information business, which has offices in Bangalore, India, and Raleigh, N.C., as well as Tucson.
Misys, 250 S. Williams Blvd., ranked 113th on this year's Star 200 list of the largest employers in Southern Arizona, with 452 full-time-equivalent positions. In January, the company laid off an undisclosed number of Tucson workers. Misys Healthcare Systems is based in Raleigh and is part of Misys PLC, based in London. Vista Equity Partners is based in San Francisco.
The company decided recently that its strength is in helping health-care providers outside hospitals manage information about patients, Misys spokesman Mike Holsinger said.

"That's really where our strong point is, and that's where we see a tremendous amount of growth in the marketplace," Holsinger said.
Maintaining the diagnostics section no longer was a good fit for the company, he said. Nor was maintaining its computerized patient records section, based in San Bernardino, Calif. That's being sold in a separate $33 million transaction to QuadraMed Corp.
In a letter to employees, R.L. "Vern" Davenport, Misys' executive vice president and general manager, said the company expects both transactions to close around October. He indicated that Vista would likely retain Misys' employees.
