Elucidation of substrate specificity in Aspergillus nidulans UDP-galactose-4-epimerase. [PDF]

open access: yesPLoS ONE, 2013
The frequency of invasive fungal infections has rapidly increased in recent years. Current clinical treatments are experiencing decreased potency due to severe host toxicity and the emergence of fungal drug resistance.

Insights into a Cancer-Target Demethylase: Substrate Prediction through Systematic Specificity Analysis for KDM3A

open access: yesBiomolecules, 2022
Jumonji C (JmjC) lysine demethylases (KDMs) catalyze the removal of methyl (-CH3) groups from modified lysyl residues. Several JmjC KDMs promote cancerous properties and these findings have primarily been in relation to histone demethylation.

Substrate specificities of SR proteins in constitutive splicing are determined by their RNA recognition motifs and composite pre-mRNA exonic elements [PDF]

open access: yes, 1999
We report striking differences in the substrate specificities of two human SR proteins, SP2/ASF and SC35, in constitutive splicing. beta-Globin pre-mRNA (exons 1 and 2) is spliced indiscriminately with either SR protein.

Functional organization of box C/D RNA-guided RNA methyltransferase [PDF]

open access: yes, 2020
Box C/D RNA protein complexes (RNPs) catalyze site-specific 2'-O-methylation of RNA with specificity determined by guide RNAs. In eukaryotic C/D RNP, the paralogous Nop58 and Nop56 proteins specifically associate with terminal C/D and internal C'/D ...

Effects of albumin and apolipoprotein C-II on the acyl-chain specificity of lipoprotein lipase catalysis.

open access: yesJournal of Lipid Research, 1993
In this study we used monoacid triacylglycerols of various acyl-chain lengths as substrates for probing the active-site structure and substrate specificity of lipoprotein lipase (LPL).

Substrate specificity of the TRAMP nuclear surveillance complexes

open access: yesNature Communications, 2020
During nuclear surveillance in yeast and human cells, the RNA exosome functions together with the TRAMP complexes. Here, the authors defined the protein composition of the TRAMP complexes and identified specific RNA binding sites for the different TRAMP ...

S-adenosyl-L-methionine: (S)-scoulerine 9-O-methyltransferase, a highly stereo- and regio-specific enzyme in tetrahydroprotoberberine biosynthesis [PDF]

open access: yes, 1985
Suspension cultures of Berberis species are useful sources for the detection and isolation of a new enzyme which transfers the methyl group from S-adenosyl-L-methionine specifically to the 9-position of the (S)-enantiomer of scoulerine, producing (S ...

Substrate specificity of prostate-specific antigen (PSA)

open access: yesChemistry & Biology, 1998
The serine protease prostate-specific antigen (PSA) is a useful clinical marker for prostatic malignancy. PSA is a member of the kallikrein subgroup of the (chymo)trypsin serine protease family, but differs from the prototypical member of this subgroup, tissue kallikrein, in possessing a specificity more similar to that of chymotrypsin than trypsin. We

Nucleotide specificity of the enzymatic and motile activities of dynein, kinesin, and heavy meromyosin. [PDF]

open access: yes, 1991
The substrate specificities of dynein, kinesin, and myosin substrate turnover activity and cytoskeletal filament-driven translocation were examined using 15 ATP analogues.
