Genetic analysis of bacterial acetyltransferases: identification of amino acids determining the specificities of the aminoglycoside 6'-N-acetyltransferase Ib and IIa proteins

Journal of Bacteriology, 1992
The aminoglycoside 6'-N-acetyltransferase [AAC(6')-I] and AAC(6')-II enzymes represent a class of bacterial proteins capable of acetylating tobramycin, netilmicin, and 2'-N-ethylnetilmicin. However, an important difference exists in their abilities to modify amikacin and gentamicin. The AAC(6')-I enzymes are capable of modifying amikacin.

Protein acetylation in archaea, bacteria, and eukaryotes [PDF]

, 2010
Proteins can be acetylated at the alpha-amino group of the N-terminal amino acid (methionine or the penultimate amino acid after methionine removal) or at the epsilon-amino group of internal lysines.

Amino acid uptake in Arabidopsis [PDF]

, 2008
Nitrogen (N) is essential for all living organisms and is considered to be the limiting factor for plant growth in many ecosystems. Although generally believed to rely on mineral N to fulfill their N needs, plants have also been found to access organic N

MOLECULAR CLONING, EXPRESSION AND FUNCTIONAL INTERACTION OF p48 SUBUNIT OF CHICKEN CHROMATIN ASSEMBLY FACTOR 1 WITH HISTONE DEACETYLASE 2 AND HISTONE ACETYLTRANSFERASE 1

Indonesian Journal of Chemistry, 2012
We cloned and sequenced cDNA encoding p48 subunit of the chicken CAF-1, chCAF-1p48, and histone acetyltransferase-1, chHAT-1 from chicken DT40 cell lines. We showed that the p48 subunit of CAF-1 tightly binds to two regions of chicken histone deacetylase

Gut microbiota–derived short‐chain fatty acids regulate group 3 innate lymphoid cells in HCC

Hepatology, EarlyView., 2022
Abstract Background and Aims Type 3 innate lymphoid cells (ILC3s) are essential for host defense against infection and tissue homeostasis. However, their role in the development of HCC has not been adequately confirmed. In this study, we investigated the immunomodulatory role of short‐chain fatty acids (SCFAs) derived from intestinal microbiota in ILC3
