enzyme

Count reviewed proteins classified with the controlled-vocabulary keyword Kinase (keywords:418) via up:classifiedWith. This is the complete route to "every kinase": a free-text search over protein names or comments for the word "kinase" would miss proteins named with the synonym "Phosphotransferase" (keywords:418's own skos:altLabel) instead, while curator-assigned keyword classification catches both consistently
