1TZ

1Tz is an alphanumeric code used as an identifier in various information systems. It does not denote a single, universal entity; its meaning depends entirely on the database or catalog in which it appears. Because it is short and non-semantic, 1Tz can be assigned to different records in different contexts, which can lead to ambiguity if the surrounding source is not known.

In practice, 1Tz may appear in contexts such as scientific databases, vendor catalogs, or internal institutional records. In protein structural databases, for example, four-character codes are commonly used to label entries, but the canonical form is typically uppercase (for instance, 1TZ) and the full entry metadata—including the organism, method of determination, authors, and date—must be consulted to identify the exact record. In other domains, 1Tz could be a product or sample identifier, a project code, or a batch number. The same code can thus refer to different things across disparate systems.

To disambiguate a reference to 1Tz, readers should identify the source database or catalog, confirm the exact capitalization, and examine accompanying metadata. Cross-referencing with related identifiers, versions, or context notes helps prevent misinterpretation. When compiling or sharing information, it is best to use the full, source-specific identifier along with its metadata.
