I wish knew best book which covers all aspects of Anti infective drug discovery process from in vitro testing to in vivo, PK, PD related aspects in a simple and up to date way.
There are so many disciplines involved in drug discovery that I doubt you will be able to find every aspect covered in any level of detail in a single book.
A lot of topics relevant to anti-infective drug discovery (and drug discovery in general), not limited to enzymology, are covered in this book by Robert A. Copeland:
EVALUATION OF ENZYME INHIBITORS IN DRUG DISCOVERY
