Publisher primary abstract https://www.sciencedirect.com/science/article/pii/S0969212600005219 : X-ray structure of Streptomyces antibioticus PNPase without bound RNA but with tungstate at catalytic sites, trimer and central channel. A possible channel role in processivity is proposed, not direct observation of RNA transit. No initials expanded.
