mRNA Decapping Enzyme
mRNA Decapping Enzyme is a decapping enzyme that catalyzes the cleavage and removal of the 7‑Methylguanosine Cap (m7G) structure at the 5' end of mRNA, generating a 5' monophosphate end and 7‑Methylguanosine 5'‑Diphosphate (m7GDP). This enzyme can decap mRNAs of various lengths and exhibits equivalent removal efficiency toward Cap‑0 and Cap‑1 cap structures. It can also convert the 5' triphosphate end of mRNA to a 5' monophosphate end, albeit with relatively low conversion efficiency. RNA with a 5' monophosphate modification is applicable to a variety of downstream experiments, including 5' RNA Ligase‑mediated Rapid Amplification of cDNA Ends (5' RLM‑RACE), RNA‑seq, and 5'→3' exonuclease digestion.

SaCas9
SaCas9 is a CRISPR nuclease derived from Staphylococcus aureus and is one of the most widely used compact Cas9 orthologs, offering distinct advantages for therapeutic genome editing. The protein consists of 1,053 amino acids with a molecular weight of approximately 120 kDa—about 25% smaller than SpCas9 (1,368 aa). This reduced size makes SaCas9 particularly well‑suited for delivery platforms with strict cargo limitations, such as AAV vectors.

OpenCRISPR‑1
OpenCRISPR‑1 is the world’s first gene editor designed entirely by artificial intelligence. The Profluent research team began by mining 26.2 terabases of microbial genomic data to construct the CRISPR‑Cas Atlas, a database containing more than 1.24 million CRISPR operons—over four times the Cas9 sequence diversity found in UniProt. Using this unprecedented dataset, the team fine‑tuned the protein language model ProGen2 to generate 4.8 million novel CRISPR‑associated protein sequences, from which OpenCRISPR‑1 emerged as the top‑performing candidate after rigorous screening and functional validation.
