UNSPSC 51172330: Exopeptidase g2

This classification denotes an enzyme with the molecular formula C31H38N4O7S, chemically known as 4-[[1-[[1-[2-[(1-benzylsulfanyl-1-oxo-3-phenylpropan-2-yl)carbamoyl]pyrrolidin-1-yl]-1-oxopropan-2-yl]amino]-1-oxopropan-2-yl]amino]-4-oxobutanoic acid but generally known as exopeptidase g2, which bears US NIH Compound Identifier 3289209. SMILES: CC(C(=O)NC(C)C(=O)N1CCCC1C(=O)NC(CC2=CC=CC=C2)C(=O)SCC3=CC=CC=C3)NC(=O)CCC(=O)O.

UNSPSC 51172330 Exopeptidase g2, a Commodity code, shows minimal alignment with recent state and local procurement activity. The single recent opportunity tagged under this code — Collin County Community Supervision and Corrections Department's RFP 2026-327 for offender specimen collection and drug testing services — concerns criminal-justice drug screening, immunoassay and confirmatory testing, and lab operations, not exopeptidase enzymes or biochemical reagents. The mismatch suggests either a tagging error in the source or a narrow, specialized use of the code that does not reflect active state and local buying patterns in biochemistry or life-sciences procurement.

Collin County, Texas posted the RFP on September 25, 2026 with a due date of July 23, 2026 (an apparent date error in the source), seeking proposals to staff specimen collection sites in Plano and McKinney, operate a randomized testing notification system, and conduct screening and confirmatory drug testing on approximately 25,031 tests annually. The contract value is estimated at $600,000 over two years with three optional one-year renewals, contingent on SAMHSA, Texas DPS, or CAP lab certification. Pricing is per-test across three service models, with no opportunity to pursue surcharges and price redetermination capped at 3.0 percent annually on September 1 anniversaries. Award depends on compliance review, proposal scoring (vendor understanding, firm qualifications, client references, and cost), and optional Phase 2 demonstrations, with the anticipated award date of August 10, 2026. The narrow recent-opportunity set and code-scope mismatch suggest this code warrants monitoring rather than active pursuit at this time.
