ABSTRACT
Cereals contain proteinaceous inhibitors of endoxylanases, which affect the efficiency and functionality of these enzymes in cereal processing. This review relates their first discovery in wheat and the subsequent purification of two distinct classes of endoxylanase inhibitors, namely Triticum aestivum xylanase inhibitor (TAXI)-type and xylanase inhibitor protein (XIP)-type inhibitors in cereals. Both inhibitor classes occur in monocots as multi-isoform families. The reported data provide an overview of the relative quantitative and qualitative variation of these inhibitors in cereals. Wheat and rye are particularly rich in TAXI-type and XIP-type inhibitors with the latter inhibitors being more abundant. Lower inhibitor levels are present in durum wheat and barley, while maize contains solely XIP-type inhibitors. No inhibitors have been isolated from rice, oats and buckwheat.
