Chitin is the second largest renewable resource only after cellulose on Earth. Chitinases are the key enzymes for degrading chitin. Chitinases of the glycoside hydrolase family 19 (GH19) mainly exist in higher plants. In recent years, microbial GH19 chitinases have been widely discovered. This paper reviews the research progress in microbial GH19 chitinases regarding their distribution, structures, enzymatic properties, and applications and prospects the research directions in the future.
