evolution | both isozymes, HS3ST3B and HS3ST2 (EC 2.8.2.29), are differently expressed in monocytes and macrophages depending on the inflammatory environment | Homo sapiens |
metabolism | heparan sulfate (HS) 3-O-sulfation can be catalysed by seven 3-sulfotransferases (HS3STs) in humans, but nevertheless it is the rarest modification in heparan sulfate (HS). Isozymes HS3ST2 (EC 2.8.2.29) and HS3ST3B exhibit the same activity in vitro. But they are differently expressed in macrophages depending on cell environment, which suggests that they may be involved in distinct cellular processes | Homo sapiens |
