Dissecting the Cytochrome P450 OleP Substrate Specificity: Evidence for a Preferential Substrate

Biomolecules, 2020
The cytochrome P450 OleP catalyzes the epoxidation of aliphatic carbons on both the aglycone 8.8a-deoxyoleandolide (DEO) and the monoglycosylated L-olivosyl-8.8a-deoxyoleandolide (L-O-DEO) intermediates of oleandomycin biosynthesis.

Evolution of substrate specificity in a retained enzyme driven by gene loss. [PDF]

, 2017
The connection between gene loss and the functional adaptation of retained proteins is still poorly understood. We apply phylogenomics and metabolic modeling to detect bacterial species that are evolving by gene loss, with the finding that ...

Phosphotyrosine Substrate Sequence Motifs for Dual Specificity Phosphatases. [PDF]

PLoS ONE, 2015
Protein tyrosine phosphatases dephosphorylate tyrosine residues of proteins, whereas, dual specificity phosphatases (DUSPs) are a subgroup of protein tyrosine phosphatases that dephosphorylate not only Tyr(P) residue, but also the Ser(P) and Thr(P ...

Predicting the substrate specificity of a glycosyltransferase implicated in the production of phenolic volatiles in tomato fruit [PDF]

, 2011
The volatile compounds that constitute the fruit aroma of ripe tomato (Solanum lycopersicum) are often sequestered in glycosylated form. A homology-based screen was used to identify the gene SlUGT5, which is a member of UDP-glycosyltransferase 72 family ...

Comparative Studies on Retroviral Proteases: Substrate Specificity

Viruses, 2010
Exogenous retroviruses are subclassified into seven genera and include viruses that cause diseases in humans. The viral Gag and Gag-Pro-Pol polyproteins are processed by the retroviral protease in the last stage of replication and inhibitors of the HIV-1

Error thresholds for self- and cross-specific enzymatic replication [PDF]

, 2010
The information content of a non-enzymatic self-replicator is limited by Eigen's error threshold. Presumably, enzymatic replication can maintain higher complexity, but in a competitive environment such a replicator is faced with two problems related to ...

Identification of sites phosphorylated by the vaccinia virus B1R kinase in viral protein H5R [PDF]

, 2000
Background: Vaccinia virus gene B1R encodes a erine/threonine protein kinase. In vitro this protein kinase phosphorylates ribosomal proteins Sa and S2 and vaccinia virus protein H5R, proteins that become phosphorylated during infection.

Substrate specificity of human MCPIP1 endoribonuclease

Scientific Reports, 2018
MCPIP1, also known as Regnase-1, is a ribonuclease crucial for regulation of stability of transcripts related to inflammatory processes. Here, we report that MCPIP1 acts as an endonuclease by degrading several stem-loop RNA structures and single-stranded
