Abstract

Chitinase proteins are extensively distributed throughout various biological systems. Plant chitinasesare found in the GH18 and GH19 families of the glycoside hydrolase gene family. Based on structure, substratespecifty, amino acid sequence similarity, mechanisms of catalysis and sensitivity to inhibitors, plant chitinases areclassifed into seven classes (I–VII). The most important chitinases are pathogenesis-related proteins which classI, II, IV, VI and VII are found in the GH19 family. In general, plant chitinases are produced by plants as an answerto pathogens and abiotic factors. They develop antifungal, antibacterial, insecticidal, nematicidal, and antiviraldefence mechanisms in plants. Kitinases are transferred into commercially important plants via gene engineeringapplications. In this way, resistant transgenic plants are being developed counter to biotic and abiotic effects. In thisreview is giving information about the properties, importance and applications of plant chitinases.

Özet

Kitinaz proteinleri biyolojik sistemlerde doğada yaygın şekilde bulunurlar. Bitki kitinazları, glikozidhidrolaz gen ailesinden GH18 ve GH19 aileleri içerisinde yer almaktadır. Yedi sınıfa (I-VII) ayrılan bitki kitinazları,yapıları, amino asit dizi benzerlikleri, substrat spesifteleri, kataliz mekanizmaları ve inhibitör hassasiyetlerinegöre birbirlerinden farklılaşırlar. GH19 ailesinde bulunan sınıf I, II, IV, VI ve VII kitinazlarının en önemlileripatojen bağlantılı proteinlerden oluşmaktadır. Genel olarak bitki kitinazları patojenlere ve abiyotik faktörlereyanıt olarak bitkiler tarafından üretilirler. Bunlar, bitkilerde antifungal, antibakteriyel, insektisidal, nematisidal veantiviral savunma mekanizmaları geliştirirler. Kitinazlar, gen mühendisliği uygulamaları aracılığıyla ticari önemesahip bitkilere aktarılmaktadır. Böylece, biyotik ve abiyotik etkilere karşı dirençli bitkiler geliştirilmektedir. Buderlemede, bitki kitinazlarının özellikleri, önemleri ve kullanımları hakkında bilgiler verilmiştir.
