Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

commentFUNCTION Acts as an atypical protein-lysine deacetylase in vitro (PubMed:31478652). Catalyzes the deacetylation of lysine residues using CoA as substrate, generating acetyl-CoA and the free amine of protein-lysine residues (PubMed:31478652). Additional experiments are however required to confirm the protein-lysine deacetylase activity in vivo (Probable). Has hydrolase activity towards various surrogate p-nitrophenyl (pNp) substrates, such as pNp-butyrate, pNp-acetate and pNp-octanoate in vitro, with a strong preference for pNp-acetate (PubMed:14672934, PubMed:31478652). May activate transcription (PubMed:14672934).CATALYTIC ACTIVITY L-lysyl-[protein] + acetyl-CoA = N(6)-acetyl-L-lysyl-[protein] + CoA + H(+)BIOPHYSICOCHEMICAL PROPERTIES kcat is 2.2 min(-1) for p-nitrophenyl-acetate (PubMed:31478652). kcat is 0.6 min(-1) for p-nitrophenyl-butyrate (PubMed:31478652). kcat is 0.2 min(-1) for p-nitrophenyl-octanoate (PubMed:31478652).SUBUNIT May interact with TAF1.SUBCELLULAR LOCATION Predominantly cytoplasmic.ALTERNATIVE PRODUCTS Ubiquitous (PubMed:14672934). Detected in spleen, thymus, prostate, testis, ovary, small intestine, colon, peripheral blood leukocyte, heart, placenta, lung, liver, skeletal muscle, pancreas and kidney (PubMed:14672934).SIMILARITY Belongs to the AB hydrolase superfamily. ABHD14 family.CAUTION The protein-lysine deacetylase activity using CoA as substrate is unclear as this protein belongs to a family of serine hydrolases, and that the reaction shown in the publication is not hydrolyzing H(2)O. Additional experiments are therefore required to confirm this activity in vivo.
