A mechanochemical approach to access the proline–proline diketopiperazine framework

open access: yesBeilstein Journal of Organic Chemistry, 2017
Ball milling was exploited to prepare a substituted proline building block by mechanochemical nucleophilic substitution. Subsequently, the mechanocoupling of hindered proline amino acid derivatives was developed to provide proline–proline dipeptides ...

Mitochondrial dynamics links PINCH-1 signaling to proline metabolic reprogramming and tumor growth

open access: yesCell Stress, 2020
Proline metabolism is critical for cellular response to microenvironmental stress in living organisms across different kingdoms, ranging from bacteria, plants to animals. In bacteria and plants, proline is known to accrue in response to osmotic and other

An Unbound Proline-Rich Signaling Peptide Frequently Samples Cis Conformations in Gaussian Accelerated Molecular Dynamics Simulations

open access: yesFrontiers in Molecular Biosciences, 2021
Disordered proline-rich motifs are common across the proteomes of many species and are often involved in protein-protein interactions. Proline is a unique amino acid due to the covalent bond between the backbone nitrogen and the proline side chain.

Proline metabolism and redox; maintaining a balance in health and disease

open access: yesAmino Acids, 2021
Proline is a non-essential amino acid with key roles in protein structure/function and maintenance of cellular redox homeostasis. It is available from dietary sources, generated de novo within cells, and released from protein structures; a noteworthy ...

Structural Basis for the Substrate Inhibition of Proline Utilization A by Proline

open access: yesMolecules, 2017
Proline utilization A (PutA) is a bifunctional flavoenzyme that catalyzes the two-step oxidation of l-proline to l-glutamate using spatially separated proline dehydrogenase (PRODH) and l-glutamate-γ-semialdehyde dehydrogenase (GSALDH) active sites ...

The regulatory mechanisms of proline and hydroxyproline metabolism: Recent advances in perspective

open access: yesFrontiers in Oncology, 2023
For diverse human tumors, growth and metastasis are dependent on proline synthesis, but the mechanisms underlying this association are not clear. Proline incorporated into collagen is primarily synthesized from glutamine.
