masticases

Masticases is not a widely established term in mainstream biochemistry or enzymology. As of now, there is no formally recognized enzyme family or standardized definition for “masticases” in major databases or reference works. In the literature, the phrase may appear only in niche or historical contexts, often as a nonstandard or speculative name for enzymes that might act on substrates related to mastic resin or other components associated with mastic gum, or simply as a misnomer for other hydrolases in discussions of natural product processing. Because of the lack of a consistent, officially endorsed definition, the precise substrate scope and enzymatic activity attributed to “masticases” can vary between sources.

Nomenclature, when it appears, follows the general pattern of enzyme names ending in -ase, but without an agreed substrate or catalytic mechanism, there is no universally accepted classification. Consequently, masticases are not listed as a discrete family in classifications such as CAZy (carbohydrate-active enzymes) or Merops (peptidases) and are not assigned a specific catalytic type by standard references.

In practice, references to masticases, if encountered, are usually found in specialized discussions related to natural product processing, resin chemistry, or industrial work involving mastic gum. Any potential application would depend on a clearly defined substrate and proven activity, such as selective hydrolysis of resin-derived compounds or biotransformation steps in flavor and fragrance processing. Until further consensus emerges, masticases should be treated as a non-standard term with context-dependent meaning.
