Aromatic rice is highly prized by consumers worldwide due to its special aromatic character. 2-acetyl-1-pyrroline (2-AP) is considered to be the single most important volatile compound responsible for aroma in aromatic rice. The present study demonstrated the effects of 2-AP, zinc (Zn) and lanthanum (La) on the 2-AP concentration of detached aromatic rice panicles in vitro. Detached panicles fr...

l-Proline concentration is primarily related to the balance of enzymatic activities of proline dehydrogenase [proline oxidase (POX)] and Delta-1-pyrroline-5-carboxylate (P5C) reductase. As a result, P5C plays a pivotal role in maintaining the concentration of proline in body fluids and inborn errors of P5C metabolism lead to disturbance of proline metabolism. Several inborn errors of proline me...

schizophrenia is a complicated, debilitative mental disorder. evidence is emerging for the association of polymorphisms in prodh gene and increased risk of schizophrenia. in the present research, we investigated relationship between of this gene and schizophrenia disease by means of a gene polymorphism using pcr-rflp technique.150 persons suffering from acute schizophrenia and 160 healthy perso...

Aim. To investigate the level of tolerance to water deficit seed generations (T1 and T4) genetically modified winter wheat with partially suppressed expression proline dehydrogenase gene (ProDH) based on analysis physiological biochemical indicators economic characteristics plants. Methods. Determination crop structure content free L-proline (Pro). Results. The Pro was studied main elements pro...

Lately, microdeletions of the 22q region, responsible for DiGeorge syndrome or velocardiofacial syndrome, have been increasingly related to neuropsychiatric disorders including schizophrenia and bipolar disorder. These manifestations seem to be related to certain genes located in the hemideleted region such as the proline dehydrogenase (PRODH) and the catechol-o-methyltransferase (COMT) genes. ...

Proline utilization A (PutA) is a bifunctional flavoenzyme with proline dehydrogenase (PRODH) and Δ1-pyrroline-5-carboxylate (P5C) dehydrogenase (P5CDH) domains that catalyses the two-step oxidation of proline to glutamate. Trifunctional PutAs also have an N-terminal ribbon-helix-helix (RHH) DNA-binding domain and moonlight as autogenous transcriptional repressors of the put regulon. A unique p...

Proline utilization A (PutA) is a bifunctional enzyme that catalyzes the oxidation of proline to glutamate. Structures of type A PutAs have revealed the catalytic core consisting of proline dehydrogenase (PRODH) and Δ(1)-pyrroline-5-carboxylate dehydrogenase (P5CDH) modules connected by a substrate-channeling tunnel. Type B PutAs also have a C-terminal domain of unknown function (CTDUF) that is...

Plants facing adverse conditions usually alter proline (Pro) metabolism, generating changes that help restore the cellular homeostasis. These organisms synthesize Pro from glutamate (Glu) or ornithine (Orn) by two-step reactions that share Δ(1) pyrroline-5-carboxylate (P5C) as intermediate. In the catabolic process, Pro is converted back to Glu using a different pathway that involves Pro dehydr...

evidence is emerging for the association of polymorphisms in prodh gene and increased risk of schizophrenia. in this project, peripheral blood sampling was obtained from 175 schizophrenia patients that their diseases were confirmed by psychiatrists. 185 healthy individuals were considered as control group. the related tests were administered on the basis of pcr-rflp. in the continuation, statis...
