ligase

[′lī‚gās]
(biochemistry)
An enzyme that catalyzes the union of two molecules, involving the participation of a nucleoside triphosphate which is converted to a nucleoside diphosphate or monophosphate. Also known as synthetase.

Towards the end of the defense process, transcription factors (WRKY and MYB) and regulatory enzyme such as E3 ubiquitin ligases will regulate the expression of defense-associated genes (18-31).
The resistance level (MICs, 4->256 mg/mL) in vanB is lower than VanA and is attributed to VanB ligase enzyme that converts D-Ala-D-Ala to D-Ala-D-Lac, perhaps due to less substitution.28 The genes of VanB gene cluster are designated as VanHB, VanXB, VanYB, VanRB, and VanSB.
E3 ubiquitin ligase NEDD4-1 plays a proto-oncogenic role in tumors through regulating the tumor suppressor PTEN expression by ubiquitination and causing its proteasomal degradation and/or nuclear translocation.[5],[12] Recent studies have found that monoubiquitination of PTEN by NEDD4-1 promotes nuclear accumulation, and polyubiquitination of PTEN inducing its degradation in the cytoplasm, but the concrete mechanism is still unclear.
