Compensatory Mutations in Predicted Metal Transporters Modulate Auxin Conjugate Responsiveness in Arabidopsis [PDF]

, 2013
Levels of the phytohormone indole-3-acetic acid (IAA) can be altered by the formation and hydrolysis of IAA conjugates. The isolation and characterization of Arabidopsis thaliana mutants with reduced IAA-conjugate sensitivity and wild-type IAA responses ...

Hormone crosstalk in wound stress response: wound-inducible amidohydrolases can simultaneously regulate jasmonate and auxin homeostasis in Arabidopsis thaliana

Journal of Experimental Botany, 2015
Highlight Wound-inducible and ER-located amidohydrolases with overlapping substrate specificities for IAA– and JA–amino acid conjugates regulate the production and destruction of active auxin and JA signals in wounded leaves.

Combined whole-cell high-throughput functional screening for identification of new nicotinamidases/pyrazinamidases in metagenomic/polygenomic libraries

Frontiers in Microbiology, 2016
Nicotinamidases catalyze the hydrolysis of the amide bond in nicotinamide to produce ammonia and nicotinic acid. These enzymes are an essential component of the NAD+ salvage pathway and are implicated in the viability of several pathogenic organisms. Its

Systematic site-directed mutagenesis to characterize subunit interactions in E. coli asparaginase II, an enzyme [PDF]

, 2005
L-asparaginases (EC 3.5.1.1) catalyze the hydrolysis of L-asparagine to aspartic acid and ammonia. Asparaginases of bacterial origin have been used for over 40 years in the treatment of acute lymphatic leukemia (ALL).

Folate Interaction With Genetic Risk for Neural Tube Defects Among Infants in Bangladesh. [PDF]

Birth Defects Res
ABSTRACT Background Neural tube defects such as spina bifida (SB) are congenital anomalies associated with significant morbidity and mortality worldwide. Environmental factors, particularly folate, modify SB risk. Based on recurrence rates of SB within families, genetic risk also contributes to SB development.

Structure-guided engineering of molinate hydrolase for the degradation of thiocarbamate pesticides.

PLoS ONE, 2015
Molinate is a recalcitrant thiocarbamate used to control grass weeds in rice fields. The recently described molinate hydrolase, from Gulosibacter molinativorax ON4T, plays a key role in the only known molinate degradation pathway ending in the formation ...

Tackling Critical Catalytic Residues in Helicobacter pylori L-Asparaginase

Biomolecules, 2015
Bacterial asparaginases (amidohydrolases, EC 3.5.1.1) are important enzymes in cancer therapy, especially for Acute Lymphoblastic Leukemia. They are tetrameric enzymes able to catalyze the deamination of L-ASN and, to a variable extent, of L-GLN, on ...

Biochemical properties of penicillin amidohydrolase from Micrococcus luteus [PDF]

Applied and Environmental Microbiology, 1979
Some biochemical properties of whole-cell penicillin amidohydrolase from Micrococcus luteus have been studied. This whole-cell enzyme showed its maximal activity at 36 degrees C at pH 7.5. It was found that the activation energy of this enzyme was 8.03 kcal (ca. 33.6 kJ) per mol, and this amidohydrolase showed first-order decay at 36 degrees C.
