PreQin

PreQin may refer to more than one concept, depending on the field.

In biochemistry, preQ1 (sometimes referenced as preQin in some texts) denotes a pre-queuosine nucleoside, specifically 7-cyano-7-deazaguanine, an intermediate in the queuosine biosynthesis pathway found in many bacteria and some archaea. Queuosine is a modified nucleoside incorporated at the wobble position of certain tRNAs and is implicated in the accuracy of codon recognition and translation. PreQ1 is produced through a series of enzymatic steps from GTP, and is subsequently converted to queuosine.

In another sense, preQin is used as a misspelling or alternative form of Preqin, a data and analytics provider for the private markets industry. Preqin collects data on private equity, real estate, infrastructure, hedge funds, and venture capital, supplying fund performance, fundraising, investor information, and market intelligence to professionals.

Because the term is ambiguous, readers should rely on context to determine which meaning is intended.
