The cysteine protease TcCYSPR04 T. cacao accumulates in senescent leaves and change the biotrophic phase for saprophytic tissues infected by M. perniciosa [PDF]

open access: yes, 2011
A cysteine proteinase named TcCYSPR04 was identified in a cDNA library of the Theobroma cacao-Moniliophthora perniciosa interaction, in the ESTtik-CIRAD database and in the cacao genome of MARS. TcCYSPR04 presents an ORF of 1068 bp encoding protein with:

Activities and properties of calcineurin catalytic domain

open access: yesChinese Science Bulletin, 2000
Calcineurin (CN) is the only protein phosphatase known to be under the control of calcium (Ca2+) and calmodulin (CaM). The enzyme consists of two subunits, the catalytic A subunit of 61 ku (CNA) and a regulatory B subunit of 19 ku (CNB). In this study, we used PCR amplication to construct a truncation consisting of only the CNA catalytic domain.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Functional Characterization of the SHIP1-Domains Regarding Their Contribution to Inositol 5-Phosphatase Activity

open access: yesBiomolecules
The Src homology 2 domain-containing inositol 5-phosphatase 1 (SHIP1) is a multidomain protein consisting of two protein–protein interaction domains, the Src homology 2 (SH2) domain, and the proline-rich region (PRR), as well as three phosphoinositide ...

The domain architecture of large guanine nucleotide exchange factors for the small GTP-binding protein Arf

open access: yesBMC Genomics, 2005
Background Small G proteins, which are essential regulators of multiple cellular functions, are activated by guanine nucleotide exchange factors (GEFs) that stimulate the exchange of the tightly bound GDP nucleotide by GTP.

p97 Disease Mutations Modulate Nucleotide-Induced Conformation to Alter Protein-Protein Interactions. [PDF]

open access: yes, 2016
The AAA+ ATPase p97/VCP adopts at least three conformations that depend on the binding of ADP and ATP and alter the orientation of the N-terminal protein-protein interaction (PPI) domain into up and down conformations.

Structure of rabbit liver fructose 1,6-bisphosphatase at 2.3 Å resolution [PDF]

open access: yes, 1999
The three-dimensional structure of the R form of rabbit liver fructose 1,6-bisphosphatase (Fru-1,6-Pase; E.C. 3.1.3.11) has been determined by a combination of heavy-atom and molecular-replacement methods.

Catalytic domains in porous catalysts

open access: yes, 2018
Understanding of the catalytic domains within porous catalysts is essential for control of these systems in order to obtain desired reaction yields and selectivities. This body of work consists of studies on two types of porous catalysts, mesoporous silica and zeolites, that can have interesting cooperative catalytic interactions between the inorganic ...

1.92 Angstrom Zinc-Free APOBEC3F Catalytic Domain Crystal Structure [PDF]

open access: yesJournal of Molecular Biology, 2016
The APOBEC3 family of DNA cytosine deaminases is capable of restricting the replication of HIV-1 and other pathogens. Here, we report a 1.92 Å resolution crystal structure of the Vif-binding and catalytic domain of APOBEC3F (A3F). This structure is distinct from the previously published APOBEC and phylogenetically related deaminase structures, as it is

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.
