SpsF is a glycosyltrnasferase implicated in the synthesis of the spore coat.
Spore coat polysaccharide biosynthesis protein F (spsF) is a glycosyltransferase implicated in the synthesis of the spore coat in a variety of bacteria challenged by stress as starvation. The spsF gene is expressed in the late stage of coat development responsible for a terminal step in coat formation that involves the glycosylation of the coat. SpsF gene mutation resulted in spores that appeared normal. But, the spores tended to aggregate and had abnormal adsorption properties, indicating a surface alteration.
