Homologies in the NH2-terminal amino acid sequences of gamma-carboxymuconolactone decarboxylases and muconolactone isomerases.

Journal of Biological Chemistry, 1980
gamma-Carboxymuconolactone decarobxylase (EC 4.1.1.44) and muconolactone isomerase (EC 5.3.3.4) mediate chemically analogous reactions in bacteria. The enzymes are inducible, and different metabolites trigger the respective syntheses of the decarboxylases in Acinetobacter calcoaceticus and Pseudomonas putida. The decarobxylases share similar oligomeric

The amino acid sequence of rabbit muscle triose phosphate isomerase [PDF]

FEBS Letters, 1973
The amino acid sequence of rabbit muscle triose phosphate isomerase was deduced by characterizing peptides that overlap the tryptic peptides. Thiol groups were modified by oxidation, carboxymethylation or aminoen. About 50 peptides that provided information about overlaps were isolated; the peptides were mostly characterized by their compositions and N-

Determination of the amino acid requirements for a protein hinge in triosephosphate isomerase [PDF]

Protein Science, 1998
AbstractWe have determined the sequence requirements for a protein hinge in triosephosphate isomerase. The codons encoding the hinge at the C‐terminus of the active‐site lid of triosephosphate isomerase were replaced with a genetic library of all possible 8, 000 amino acid combinations.

A Critical Test of the Electrostatic Contribution to Catalysis with Noncanonical Amino Acids in Ketosteroid Isomerase [PDF]

Journal of the American Chemical Society, 2016
The vibrational Stark effect (VSE) has been used to measure the electric field in the active site of ketosteroid isomerase (KSI). These measured fields correlate with ΔG(⧧) in a series of conventional mutants, yielding an estimate for the electrostatic contribution to catalysis (Fried et al. Science 2014, 346, 1510-1513).

The phycoerythrobilin isomerization activity of MpeV in Synechococcus sp. WH8020 is prevented by the presence of a histidine at position 141 within its phycoerythrin-I β-subunit substrate

Frontiers in Microbiology, 2022
Marine Synechococcus efficiently harvest available light for photosynthesis using complex antenna systems, called phycobilisomes, composed of an allophycocyanin core surrounded by rods, which in the open ocean are always constituted of phycocyanin and ...

Insight into PreImplantation Factor (PIF*) mechanism for embryo protection and development: target oxidative stress and protein misfolding (PDI and HSP) through essential RIKP [corrected] binding site. [PDF]

PLoS ONE, 2014
Endogenous PIF, upon which embryo development is dependent, is secreted only by viable mammalian embryos, and absent in non-viable ones. Synthetic PIF (sPIF) administration promotes singly cultured embryos development and protects against their demise ...

Crystal structures of Triosephosphate Isomerases from Taenia solium and Schistosoma mansoni provide insights for vaccine rationale and drug design against helminth parasites.

PLoS Neglected Tropical Diseases, 2020
Triosephosphate isomerases (TPIs) from Taenia solium (TsTPI) and Schistosoma mansoni (SmTPI) are potential vaccine and drug targets against cysticercosis and schistosomiasis, respectively.

Post-duplication charge evolution of phosphoglucose isomerases in teleost fishes through weak selection on many amino acid sites

BMC Evolutionary Biology, 2007
Background The partitioning of ancestral functions among duplicated genes by neutral evolution, or subfunctionalization, has been considered the primary process for the evolution of novel proteins (neofunctionalization).

Amino acid sequences around the cysteine residues of rabbit muscle triose phosphate isomerase [PDF]

Biochemical Journal, 1971
1. The nature of the subunits in rabbit muscle triose phosphate isomerase has been investigated. 2. Amino acid analyses show that there are five cysteine residues and two methionine residues/subunit. 3. The amino acid sequences around the cysteine residues have been determined; these account for about 75 residues. 4. Cleavage at the methionine residues
