reduction processes biocatalyzed by Vigna unguiculata
Tetrahedron-asymmetry, 2010Co-Authors: Ayla M C Bizerra, Gonzalo De Gonzalo, Ivan Lavandera, Vicente Gotorfernandez, Marcos Carlos De Mattos, Maria Da Conceicao F De Oliveira, Telma L G Lemos, Vicente GotorAbstract:Abstract Whole cells from the Brazilian beans feijao de corda (Vigna unguiculata) have been employed as biocatalysts in different bioreduction processes. Good to excellent selectivities can be obtained in the reduction of aromatic and aliphatic ketones, as well as β-ketoesters, depending on the conversions and the chemoselectivity on the substrate structure. This biocatalyst was also able to reduce the nitro moiety of different aromatic nitro compounds, showing as well enoate reductase activity, and chemoselectively catalyzing the double bond reduction of 4-phenyl-3-buten-2-one with moderate conversion.

purification of angiotensin i converting enzyme inhibitory peptides from a cowpea Vigna unguiculata enzymatic hydrolysate
Process Biochemistry, 2011Co-Authors: Maira Rubi Seguracampos, Luis Chelguerrero, David BetancuranconaAbstract:Abstract Angiotensin I-converting enzyme (ACE) inhibitory peptides were isolated and characterized from cowpea (Vigna unguiculata L. walp). Cowpea protein isolate was prepared by wet fractionation, extensively hydrolyzed with Flavourzyme® and filtered through four molecular weight cut-off (MWCO) membranes in a high performance ultrafiltration (UF) cell. The ultrafiltered fraction with the highest ACE inhibitory activity was purified using gel filtration chromatography followed by reverse-phase high performance liquid chromatography (RP-HPLC). The cowpea peptide inhibition (IC50) values were similar to those reported for many other natural ACE inhibitory peptides. The

the genome assembly of asparagus bean Vigna unguiculata ssp sesquipedialis
Scientific Data, 2019Co-Authors: Ru Zhang, Xuemei Ni, Yangzi Wang, Xiao Dong, Zhe Zhang, Yong Li, Wen Wang, Huanming Yang, Chanyou ChenAbstract:Asparagus bean (Vigna. unguiculata ssp. sesquipedialis), known for its very long and tender green pods, is an important vegetable crop broadly grown in the developing Asian countries. In this study, we reported a 632.8 Mb assembly (549.81 Mb non-N size) of asparagus bean based on the whole genome shotgun sequencing strategy. We also generated a linkage map for asparagus bean, which helped anchor 94.42% of the scaffolds into 11 pseudo-chromosomes. A total of 42,609 protein-coding genes and 3,579 non-protein-coding genes were predicted from the assembly. Taken together, these genomic resources of asparagus bean will help develop a pan-genome of V. unguiculata and facilitate the investigation of economically valuable traits in this species, so that the cultivation of this plant would help combat the protein and energy malnutrition in the developing world.
